oh ok
So, we bring it to the top like that.
so now its 3x^3y^-2
Chai T. Rex
The one on top is still there.
so bascially its just one y
oh ok
ahh gotcha
So, we write what we had and we write what we're including.
So, we have yy⁻².
So, we add the exponents.
What exponent do you get?
imposter sus
-2?
No, the y on the left.
3..
No, that's the x.
im realy not sure
OK, what is on the top?
3x^3yy^-2
OK, so if something doesn't have an exponent, the exponent is 1.
im so dumb
@hot island Please stop interrupting.
so if theres no number next to the letter it means its 1
@hot island u can listen but not type
@shy oasis Yes, the first power means you have one copy of the thing.
And we have one copy of y.
yes so now we get y^-3
2y-²
<@&268886789983436800> Repeated interruptions with incorrect information after repeatedly being asked to stop by both of us by @hot island
@shy oasis No.
-1
Right.
sorry i just get confushed when there is a negative number and theres a addition sign
@hot island Knock it off.
@oak chasm
muted
where were we
Thanks.
Chai T. Rex
yes
So, now we have a negative exponent on top, so we can move it to the bottom.
How do we do that?
Right!
oh
Chai T. Rex
does the 3x^3 become 27x
Nope, remember that the exponent is like 3(x³).
It only applies to the thing right next to it.
Right.
That's also true with signs.
-x² is -(x²).
That's because the sign is like -1 times the number.
-1x² is -1(x²).
yea
So -x² is -(x²).
so what do i do for 3x^3 now
Oh, that's it.
You have each variable on only one side of the fraction.
You have no negative exponents.
And the nonvariable numbers are reduced.
3/4 is a simplified fraction.
oh so thats my answer?
Yes, that's right.
Sure.
ur a really good helper
Chai T. Rex
i think so
OK, what do you get?
2/7
Chai T. Rex
OK, now we have x² under the square root, too.
Chai T. Rex
You know about absolute value?
i do but i forgot
It converts negative numbers to their positive version and leaves other numbers alone.
|-3| = 3, |0| = 0, and |3| = 3.
but we dont have to because its already a positive
how is x a negative
That's an example I gave, not what x is in your problem.
oh ok
If x = -3, then x is negative.
yes
Also, if x = -3, then -x is positive.
yea
OK, so back to the problem.
Chai T. Rex
Chai T. Rex
What do we do first to get the result of that?
not really sure
Well, inside the square root, we have just one thing to do.
The exponent.
What's (-3)²?
Chai T. Rex
What's the square root of 9?
3
ohhh
Chai T. Rex
Chai T. Rex
Do you see how we got that?
No, it's because of what we just learned.
If you have x² under the square root, you take it out of the square root as |x|.
oh ok
And if you have 28 under the square root, 2 comes out and 7 stays in.
So, the 2 and the |x| are outside.
7 is left inside.
Chai T. Rex
Oh, that's it.
ohg
You can't do anything else with the stuff under the square root.
x is an angle, the line with length 10 is an angle bisector. How can I find r and s (preferably without trig cuz I don't understand it)
@candid thistle Sorry, channel is busy.
Eat water it's good
Okay, lemme ask somewhere else
@shy oasis This is correct ^
Chai T. Rex
yes
Which is also equal to ...
Chai T. Rex
Now simplify :)
Do you see why they're equal?
yea
OK, now we do what we learned a while back.
simplify!
You have two things multiplied in the parentheses.
So, you take each of them to the power outside of the parentheses.
$(ab)^c = \text{what?}$
Eat water it's good
so now i take 15 out>
im not sure what to take out
OK, so you don't take anything out.
yea
What you do is you have two things multiplied together in parentheses all to a power.
yes
do we do 8x^1/3?
Nope.
See this ^
yes
So, what's a in our problem?
8
What's b?
15
Nope.
x
What are we multiplying with 8?
1/3
Nope.
Chai T. Rex
im not sure what b is
b is inside the parentheses, right?
1/3 is outside.
there are two terms inside the parentheses, these are-
x^15
Good.
$(8 \cdot x^{15})^{1/3}$
(8)^1/3
Ooh so if you have (\text{test}) then it is a light background, otherwise $\text{test}$ gives a dark background?
(x^15)^1/3
And simplify-
sorry im getting confused cuz theres two people typing at once
Sorry, I will stop
In a private message with @ocean seal, say ,texconfig color help
@shy oasis OK, now put them next to each other.
Chai T. Rex
Right, so the answer is 2x⁵.
Chai T. Rex
3/4
Nope.
Because 2² = 4.
Well, let's do it this way.
Factor 12 into prime powers. What do you get?
idk
OK, what are the first few primes?
2,3,5,7
OK, is 2 in 12?
yes
6
Is 2 in 6?
yes
3
Is 2 in 3?
no
yes?
OK, divide 3 by 3.
1
correct
OK, now square root is the second root, right?
yes
So the primes have to leave in matching groups of two of the same prime.
Two because it's the second root.
If it was a cube root, the third root, we'd need groups of three of the same prime.
If it was the 100th root, we'd need groups of 100 of the same prime.
Does that make sense?
yea
so like it has to be the same number
Is there a group of two of the prime 2?
like 2 2
Right.
100 and 100
Or 7 7
What stops at 1?
wait nvm
That was for getting the prime factorization.
This is a different step after that's done.
Now we have the primes, 2, 2, and 3.
It's the second root, so we need groups of two of the same prime.
Do we have any groups of two of the same prime?
2 2
Good, so that's one group of 2s.
That group left the square root.
We have 3 as the primes left over.
Do we have any groups of two of the same prime?
no
OK, so one group of 2 left. 3 couldn't get out.
Chai T. Rex
Let's try it with 48.
Chai T. Rex
What are the primes in 48?
Good, go on.
24 divided by 2 is 12
12 divided by 2 is 6
6 divided by 2 is 3
ohhh i see the pattern now
4
2 groups
1
Nope.
none
1
No.
none
1
Right.
its just 3 now
Chai T. Rex
is this part of the problem?
No, this is so you know how to simplify square roots of integers.
it makes sense
OK, so let's go back to the problem.
We have nine xs, right?
OK, so how many groups of two xs are there?
4
How many are left over?
1
Chai T. Rex
Does that make sense?
yea
OK, can x⁴ be negative?
Yes, that's right.
And since it's a variable, it gets an absolute value in case it's negative.
Now, can x⁴ be negative?
no
OK, so the absolute value won't change what's inside since it's not negative.
It does nothing.
Chai T. Rex
ok
So, let's combine everything.
Chai T. Rex
We combine the parts in the square roots.
Chai T. Rex
We combine the 3 and 2. We combine the x powers.
Chai T. Rex
Good.
Thanks.
Oh, I'm not really on Twitch (at least as a streamer).
do u like mod?
What's mod?
its someone who helps keep weirdos out of chat
Oh!
bascially perms to ban people
Yeah, they help keep things running smoothly.
how to remove log on both sides?
ok so that was the answer?
do u know how to graph?
ok
sorry if im asking for help too much
OK, so that's in standard form.
yes
The trick with graphing that is that you can find the x and y intercepts.
Do you know how?
yes
OK, what are the intercepts?
x, y?
Yes, what is the x intercept?
Nope.
oh
Here's how you do it.
y intercept is on the y axis.
The y axis is where x = 0.
Like if you look at the points on the y axis, you have things like (0, 1).
That's 1 up from the origin.
That's on the y axis.
You have things like (0, -10000).
That's 10000 down from the origin.
That's on the y axis.
Does that make sense?
OK, so x = 0 on the y axis. The y intercept is on the y axis.
So for the y intercept, x = 0.
3x + 2y = -6.
Fill in x with (0).
Because x = 0.
3(0) + 2y = -6.
its 2x+3y=-6
0 + 2y = -6
Oh, sorry.
2x + 3y = -6
2(0) + 3y = -6
0 + 3y = -6
3y = -6
See how the x term disappeared?
I didn't add anything.
oh ok
x = 0 on the y axis, right?
yes
The y intercept is on the y axis, right?
yes
OK, so the y intercept will have x = 0 since it's on the y axis.
2x + 3y = -6
2(0) + 3y = -6
Do you see how I filled in x with (0)?
yea
OK, so to get one of the intercepts, you erase the other variable's term.
2x + 3y = -6
y intercept, so erase x term
3y = -6
2x + 3y = -6
now i do -6 divided by 3
x intercept, so erase y term
2x = -6
With standard form, to find an intercept erase the term with the other variable and solve.
yea
So, what's the y intercept?
3
Nope.
-3
Nope.
-2
What's the equation?
-6 divided by 3\
OK, what's the x intercept?
-3
Right.
So, mark the y intercept at (0, -2).
Mark the x intercept at (-3, 0).
Tell me when you've marked those points.
wait so its just a straight line then
Yes, connect those points with a straight line.
And also draw the line all the way to the edges of the graph.
The y intercept is on the y axis.
The x intercept is on the x axis.
You have them both on the y axis.
That's probably close enough.
Better to do it with a ruler, but if you don't have a ruler, you can do it this way.
Hello
@tight haven Sorry, channel is busy.
Got it
So, going from the y intercept to the x intercept, you go up 2 and left 3, right?
OK, so from there, go up 2, left 3 again and mark that point.
Then, from there, go up 2, left 3 again and mark that point.
And so on until you can't.
wait i got it right right?
yea
OK, now go back to the y intercept.
its on (-3,0)
What's on (-3, 0)?
x intercept
OK, start at the y intercept.
You have to go up 2 and left 3 to get to the x intercept, right?
yea thats what i did
yes
OK, to get from the y intercept to the x intercept, you go up 2 and left 3, right?
yes
ok
The x intercept.
Go up 2, left 3 from there.
That's a point you haven't marked yet, right?
i marked it already
OK. From that point, go up 2, left 3.
Mark that point.
How many points have you marked?
OK, now mark the fourth point.
Then, keep going. When you reach the end of the graph,
Start at the y intercept again.
done
Go down 2, right 3.
Mark the point.
Keep going down 2, right 3 until you reach the end of the graph.
i thought u said go up and left 3
OK, what point did you mark last?
the third one
Did you mark a fourth one?
OK, the last point you marked is the fourth point.
So, how do you get from the fourth point to the third point?
2 up and left 3
No.
Look at the actual fourth point.
Look at the actual third point.
How do you get from the fourth point to the third point?
im not sure
Do you go up or down?
up
No.
I didn't say from the third point.
x
I asked how do you get from the fourth point to the third point.
In that question, what point do you start at?
third point
new york
If I ask you how to get from the fourth point to the third point, what point do you start at?
Nope.
right*
Right.
Do you see how the points are neighbors to both the point 2 up and 3 left and the point 2 down and 3 right?
yea
OK, so start at the y intercept.
Go 2 down and 3 right. Mark the point.
Go 2 down and 3 right. Mark the point.
And so forth.
sorry if im interrupting but i came across these Singaporean Isometric questions and i dont quite understand em
@cerulean vine Sorry, channel is busy.
so i keep doing the same thing
oh k
so i keep going?
Yes until you go off the graph.
Express
−𝟏𝟐𝟓
𝟔𝟒
as an exponent
answer
ok
@errant jolt Sorry, channel is busy.
@shy oasis So, basically you find out how to get from one intercept to another.
You keep moving like that until you go off the groph.
so i got it right?
Then you go back to the start and go the other direction.
Yes, except the line on the far right doesn't exactly go through the last point.
yea this is for practice
Oh, OK.
Oh, good.
what about 1d
OK, so standard form has the variables on the left and the constant on the right.
So, move the constant to the right.
not sure how to do that
Do you know how to move a term to the other side of an equation?
i kinda forgot
0 = x - 6?
No.
im not really sure
What do you do to both sides?
is this channel free?
nvm
It's connected to the rest by subtraction.
The opposite of subtraction is addition.
Add 6 to both sides.
Does that make sense?
x=0
kind of
oh yea
1/2x-6 right?
im not really sure
sorry which from is this again
Sorry?
form*'
1
No.
Have you done algebra before?
What does x - 6 mean in algebra?
but i kinda forgot
What does x mean?
1
idk
It's a variable.
It stands for a number.
Do you remember that from learning algebra?
I didn't ask what number it equals.
I asked what it was.
What does it mean?
It's a variable.
yes
unknown number?
No.
i really dont know what it means
Do you remember what - means from grade school?
Have you seen a subtraction problem before?
yes
What does - miean?
u mean median?
i do
What does the - in a subtraction problem mean?
minus sign
minus sign
subtract
Subtract what from what?
x from 6
No., 6 from x.
So, x - 6 means to subtract 6 from x.
yes
How is 6 connected to the rest of x - 6?
not sure
It's being subtracted from it.
What's the opposite of being subtracted from something?
adding
Being added to it.
yes
x
Do you see how it's not on that side now?
yea
OK, so we need to do the same thing to both sides.
x - 6 = 0
We add 6 to both sides.
x - 6 + 6 = 0 + 6
What does that simplify to?
x=6
OK, so that's how you move a term to the other side.
ok
So, let's go back to the problem.
ok
add 6 to both sides
OK, what do you get when you do that?
do we add 6 to -6 and 0?
No, you add 6 to both sides.
to what
To the left side and to the right side.
@errant jolt Sorry, channel is busy.
Could you please help me
Yes.
You add 6 to both sides.
It has the left side plus 6.
It has the right side plus 6.
x=-6y+12
ok
This is because doing the stuff in parentheses first and then doing the addition is the same thing as without parentheses.
You're going to do everything that used to be in parentheses first anyway.
OK, so simplify the left side.
x/2 + 3y
ax + by = c
Wher a, b, and c are integers that don't all have a common factor.
1/2 isn't an integer.
2
So, multiplying it by 2 will work.
But you can't just multiply part of it by 2.
You have to multiply both sides by 2.
are we allowed to go the mathematics vc
I don't have a microphone.
oh ok
But you see how 1/2 can be changed to an integer by doubling it?
oh alright
so 1/2 x 2?
Im the cia
Yes, but with an equation, you can't just multiply one part of it by 2.
You have to do the same thing to both sides.
So, multiply both sides by 2.
hi guys
2(1/2 x + 3y) = 2(6)
so what does that turn out
@pastel panther Sorry, channel is busy.
=12
What about the left side?
Do you know the distributive property?
a(b + c) = ab + ac
what do i do next
Do you see how the distributive property works?
yea
OK, how does it work?
i multply 2 to 1/2 and 3
so 1/2 by 2?
x
6
No.
idk
6y
7y
x+ 6y
yes
Now it's in standard form.
yup
Now you can find the x and y intercepts.
But let's recap.
1/2 x + 3y - 6 = 0
That's what we started with.
That's not in standard form.
We have the variables on the left and the constant on the right in standard form.
So, we moved the constant to the right side.
Then we fixed everything to have integer coefficients.
Then it was in standard form.
So now, what are the intercepts?
x=6
ok
What is y at the x intercept?
0
Fill in (0) for y.
so its (6,0)
im not getting you
x+6(0)=12
i geet 6
That's not a simplified equation.
I didn't ask you to solve it.
I said to simplify it.
@golden basalt Sorry, channel is busy.
Ok
12/6
That's not an equation.
That doesn't have an equal sign.
So it can't be a simplified equation.
I didn't ask for you to solve for x.
I said to simplify it.
x=6
No.
im not sure
yes?
no
Simplify it.
0
12
How?
x
What?
You said 12 can be simplified.
I asked how, which means to give me a way it can be simplified.
x is not a way it can be simplified.
12/0?
What's that evaluate to?
12
No.
0
What can you multiply by 0 to get 12?
nothing
Then 12/0 isn't a number.
yes
hey guys im new here andi have a doubt
@royal anvil Sorry, channel is busy.
