HELP!! My final is tomorrow 😭

[unborn owl]

Alright uh

Let's start with qn 4

How far along are you with qn 4

[small heron]

This is what I got

So far

[unborn owl]

Qn 4 seems good

Qn 5 not so much

Maybe look at that again

[small heron]

What is wrong?

[unborn owl]

You divided by 12x^2 instead of 12x^-2

@small heron

[small heron]

So will the answer then be 6x^5

[unborn owl]

Oh nvm

I think you just forgot to put the negative sign

Your final answer is still correct

[small heron]

Oh ok!

[unborn owl]

Wait nvm

What is 6/12

[small heron]

6

[unborn owl]

Uh I mean 6 divided by 12

[small heron]

Oh it’s 1/2?

[unborn owl]

Yea I mean

[small heron]

So is my answer wrong

[unborn owl]

Yea

It's uh x^9/2

[small heron]

Huh

I don’t understand

How u got the answer

[unborn owl]

Alright uh so

$\frac{6x^7}{12x^{-2}}=\frac{6}{12}\cdot\frac{x^7}{x^{-2}}$

[uncut hatch]

Muus

[unborn owl]

This you can agree with yes? @small heron

[small heron]

Yeah 👍

[unborn owl]

So what is 6/12

[small heron]

1/2

[unborn owl]

What is x^7/x^-2?

[small heron]

x^5?

[unborn owl]

No notice the negative exponent on the denominator and try again

[small heron]

Uhh is it x^-5 then?

[unborn owl]

No not quite either

x^a/x^b=x^(a-b)

You get this?

[small heron]

Does it mean x^7-2

[unborn owl]

Ok let's go back to uh

7th grade ish

What is 7-(-2)

[small heron]

It’s 9

[unborn owl]

Yes

[small heron]

Ok so x^9?

[unborn owl]

Yes

[unborn owl]

So what is this whole thing equal to

[small heron]

1/2x^9

[unborn owl]

No

Uh

Try again

Idk probably just careless

[small heron]

I am confused

[unborn owl]

Ok

What is (1/2)*5

Just an example

[small heron]

Idk man

5/2?

[unborn owl]

Yea

Now replace that 5 with x^9

[small heron]

So x^9/2

[unborn owl]

Yea

That's the uh answer

Alright so

You wanna try the rest on your own

[small heron]

Ok I will try it

Is the 6 one correct

[unborn owl]

No

You accounted for the two sides of 3*3

But not for the other pairs

Also 2(3*3) is not equal to 9

[small heron]

Where did I write that one

[unborn owl]

Oh nvm

That's qn 7

Qn 6 is correct

[small heron]

Ok so 7 incorrect?

[unborn owl]

Yea

[small heron]

I got 18+48x

[amber lantern]

@small heron you're literally learning and not revising day before the exam 😭

u still got time, goodluck

[small heron]

Uhh I already took my exam it was not too bad🥲👍
