mind explaining to me how 2 goes to the other sideand 4 dissapearsand how x+4 gets unrooted

[vagrant wadi]

helpppppp

[lethal osprey]

@vagrant wadi

hey

so

[vagrant wadi]

yo

[lethal osprey]

you should know the property of exponents that if there are two expressions in which the bases are equal and the expressions are said to be equal

then their powers must be equal

like 729 = 3^x

here you need to bring 729 as an exponent of 3 to be able to find the value for x

729 = 9^3 = 3^6

therefore x is 6

similarly in your question

4^(x+4) can be written as 2^2(x+4)

[vagrant wadi]

ah ok

[lethal osprey]

and then you can equate the powers due to the equality sign in the expression

did you understand?

[vagrant wadi]

wait so i still dont get hot x+4 gets unrooted

[lethal osprey]

unrooted?

what do you mean exactly

[vagrant wadi]

the expression x+4 goes from being the root of 4 to being multiplied by 2

[lethal osprey]

yeah

just like the expression i gave you to understand as an example

729 = 3^x

can you solve for x like the way i explained?

then further we can try to do your question

[vagrant wadi]

you just have to make 729 squared just like the expression 3^x

i explained that poorly

[lethal osprey]

correct

729 can be written as 3^(6)

[vagrant wadi]

mhm

which since is equal to each other x must be 6

[lethal osprey]

you can cross check my multiplying 3, 6 times

correct!

[vagrant wadi]

im still really confused

[lethal osprey]

similar is the solving mechanism for your question

in your question you can basically solve it via two methods

[vagrant wadi]

can you explain to me step by step?

[lethal osprey]

first will be the method i explained to you

[vagrant wadi]

k

[lethal osprey]

and second will be taking log base 2 or 4 both sides

since you are solving questions for exponents i guess you do not understand what logarithm is

[vagrant wadi]

ig

[lethal osprey]

okay 1 sec

4^(x+4) = 2^(x)^2
(2^2)^(x+4) = 2^(x)^2 (since 2^2 = 4)
2^{2(x+4)} = 2^(x)^2
as the bases in a exponential equation like here are equal the powers have to be equal
there fore we write,

2(x+4) = x^2

from here you just solve the quadratic equation to get its roots i.e value for x

did you understand now?

[vagrant wadi]

O SHUT YES I GET IT

mb i this i was confusing this question with another one

[lethal osprey]

alright no worries!

[vagrant wadi]

cuz im doing another one as we speek

and can u help with another?

[lethal osprey]

yeah you gotta focus in math

sure

[vagrant wadi]

cuz this one is pissing me off even more

[lethal osprey]

hit it

[vagrant wadi]

i got up to this

[lethal osprey]

similarly

[vagrant wadi]

thats all

[lethal osprey]

wait wait

[vagrant wadi]

im not even sure thats correct :/

[lethal osprey]

the thought process for questions like these is majorly

that you see soo many 7s right?

[vagrant wadi]

yea ig

[lethal osprey]

try to answer my questions so that i can explain you better

yeah correct

so try to make the bases equal that it 7

now you need to try to make 16807 in the form of 7

its a tedious work

[vagrant wadi]

waiiit

nah

surley not

holly fuuuuuuuuu]

[lethal osprey]

tell me how many times you need to multiply 7 to get 16807

[vagrant wadi]

wb the (7x)^2

[lethal osprey]

you did that wrong

its 7^(x^2)

not 7x^(2)

its 7 raised to x sqaured

not 7x raised to 2

[vagrant wadi]

wait what

but the picture

7^5=16708

btw

[lethal osprey]

the first picture is the question right?

correct

[vagrant wadi]

yea

[lethal osprey]

look at the denominator carefully

its 7 raised to x squared

[vagrant wadi]

is it not just 7^2x

[lethal osprey]

it is

look at the second picture you sent

its not what you are saying right now

[vagrant wadi]

how is it 7^x^2

[lethal osprey]

oh my bad

lmao

[vagrant wadi]

e

[lethal osprey]

i saw it wrong

[vagrant wadi]

lol alg

just start off from where u made the mistake

[lethal osprey]

its 7^x squared

[vagrant wadi]

yea

[lethal osprey]

now as you made 16807 in terms of 7

just equate the powers for x like the previous questions

[vagrant wadi]

hold up

[lethal osprey]

https://tenor.com/view/capybara-ok-he-pull-up-capybaras-car-meme-gif-25675731

[vagrant wadi]

wait im so confused on what i did for the 2nd question

[lethal osprey]

start again

[vagrant wadi]

what in the hell

alr

gimme a sec

[lethal osprey]

just chill out bruh

dont get tensed up

[vagrant wadi]

wait did i mess up?

idk at this point :/

[lethal osprey]

yeah you did in the first attemot which you sent me

[vagrant wadi]

i canttt i need to do this fast

cuz i gotta gety my sleep

im always tired

[lethal osprey]

i feel you

[vagrant wadi]

so whats the first step in

[lethal osprey]

just concentrate on the LHS

[vagrant wadi]

k

[lethal osprey]

do what you can

what you know about the exponential properties

for the LHS

and then send me

[vagrant wadi]

7^x times 7^1+2x can turn into 7^x+1+2x

[lethal osprey]

the answer is 4 right?

correct

and then do the same for denominator

[vagrant wadi]

yes

7^2x

dividing means subtracting

sooo

[lethal osprey]

but you need to subtract

correct

when you are done resolving the LHS

[lethal osprey]

try to bring RHS in terms of LHS so that you can somehow find x

man typing this much is hard fr

[vagrant wadi]

like? 🙃

[lethal osprey]

like try to recall how i said you should do

[vagrant wadi]

can i not just do this?

[lethal osprey]

do what

[vagrant wadi]

wait shi nvmd

[lethal osprey]

correct

[vagrant wadi]

oh

its correct?

[lethal osprey]

yeah

[vagrant wadi]

alr :)

[lethal osprey]

u subtracted the power in the denominator from the numerator right

[vagrant wadi]

yea

[lethal osprey]

thats what you do in a fraction when you have the same bases

[vagrant wadi]

ahhh ic now

its all comming together

[lethal osprey]

yeye

[vagrant wadi]

but the one from before 2(x+4)=x^2

i still dont know how to find x 💀

[lethal osprey]

did you learn quadratic equations?

[vagrant wadi]

yes

but im a dumbass at quadratics

[lethal osprey]

then just solve the quadratic

take all the terms on one side

and just solve like a normal quadratic

[vagrant wadi]

e

ur making it sound so simple lol

wait its two numbers that multiple to make the middle number right?

and add to the right number

[lethal osprey]

no

its the opposite

2 no.s which make the right number and add to the middle number

or just use the quadratic formula if you are unable to create factors

[vagrant wadi]

oh alr

MY BRAINS GOING INTO OVERLOAD

[lethal osprey]

bruh

[vagrant wadi]

JK

im just dumb 🙃

[lethal osprey]

same here

we are the same

[vagrant wadi]

i just wanna get smarter

[lethal osprey]

fr

[vagrant wadi]

btw while i finish off these questiions can u take a look at this for me?

havent even read it

[lethal osprey]

try it first

[vagrant wadi]

ill work on it after these ones

[vagrant wadi]

will do

[lethal osprey]

are you done?

what similarity do you find in the question?

[vagrant wadi]

ok so apparently this also has to do with quadratics

[lethal osprey]

correct

[vagrant wadi]

you can turn the similar terms like 2^x into say a

[lethal osprey]

yes

[vagrant wadi]

it would be a^2-5a+4=0

[lethal osprey]

like this method you can also solve biquadratics without any cubic terms or it gets messy

do you know what they are?

[vagrant wadi]

(x+1)(x-1)

difference of two squares or perfect squares?

is that what ur saying?

ik that

[lethal osprey]

nah good guess

[vagrant wadi]

oh

then idk what biquadratics are

[lethal osprey]

a polynomial with a degree of 4

[vagrant wadi]

this is correct tho right/a^2-5a+4=0

[vagrant wadi]

nty

no clue what on earth that is

[lethal osprey]

like quadratic is a polynomila with a degree 2

[vagrant wadi]

im a year 9 currently on headstart learning yr 10 stuff

[lethal osprey]

no worries it is usually taught in college

[lethal osprey]

wtf i learnt all this in like 6th grade

[vagrant wadi]

DAM

[lethal osprey]

the things you are asking me ?

are you from the US

[vagrant wadi]

no im in australia

[lethal osprey]

ay

i used to live in perth

[vagrant wadi]

BUT HOLLY SHIT IN YEAR 6 WE DIDNT KNOW WHAT QUADRATICS ARE

AND UR HERE LEARNIN THIS STUFF

[vagrant wadi]

nice

[lethal osprey]

yeah im in yr 12

as you say

[vagrant wadi]

dang

[lethal osprey]

so yeah basically you solve for a

find its roots and then equate it with 2^x as you took a as 2^x

now there is a really good place where you will be stuck and then ill explain you that really well which is a main theory for polynomials

[vagrant wadi]

help

so i now have 2x-4=0 and 2x-1=0

so its x=2 for the first one

but for 2x-1=0 idk what to do

2x=1

x=1/2

but answers say thats incorrect

[lethal osprey]

lmao

no

[vagrant wadi]

what did i dooo

[lethal osprey]

tell me when (any constant)^x becomes 1

[vagrant wadi]

0

[lethal osprey]

exactly

that is what is happening over here

[vagrant wadi]

so im basically just guessing?

[lethal osprey]

in the second part

no

you are understanding

[vagrant wadi]

oooh 2x=(2)^x

[lethal osprey]

yeah

[vagrant wadi]

that what ur saying?

dam

[lethal osprey]

wait n

no

wtf

[vagrant wadi]

e

😂

[lethal osprey]

2x is not equal to 2^x

its totally different

[vagrant wadi]

then how would i know what to do

[lethal osprey]

you typed it wrong

[vagrant wadi]

then tell me :/

[lethal osprey]

didnt they teach you a^0 = 1 where a is any number

[vagrant wadi]

they did

[lethal osprey]

then solve for 2^x = 1

[vagrant wadi]

but its currently 2x

not 2^X

or am i trippin

[lethal osprey]

by which number should i raise 2 so that i get 1

u tripping

[vagrant wadi]

hold up lemme see

[vagrant wadi]

probs

[lethal osprey]

you considered a = 2^x

not 2x

look at the question

[vagrant wadi]

yup im trippin

[lethal osprey]

alright i gotta study rn

message me if you have any doubts

sorry

[vagrant wadi]

for the first one its just 2^x=4

x=root4

oops

mb

wait hold up

wtf

nvmd

yes

[vagrant wadi]

so then x=2

@lethal osprey for the 2nd one where 2^x-1=0

theres 2 answers

x=2 and x=0

[lethal osprey]

correct

[vagrant wadi]

wait is there?

oh yea there is

how do i get x=2 for the 2nd again? i forgot

[lethal osprey]

finally

[vagrant wadi]

how i did it

[lethal osprey]

wdym

[vagrant wadi]

so yk how x=0 right?

is there an equatioin for it? where 2^x -1=0?

or do you just like DO IT

@lethal osprey

[lethal osprey]

wdym

[vagrant wadi]

for how is 2^x -1=0? turned into x=0

whats the steps

or is it just like

2^x=1

and then your just suppsoed to know that x=0

[lethal osprey]

bruh

i just told you

[vagrant wadi]

ITS 11:50 IM SORRY

[vagrant wadi]

where

[lethal osprey]

anything raised to the power 0 is 1

[vagrant wadi]

IK

[lethal osprey]

this is a property i asked you and you said you knew

[vagrant wadi]

SO ARE YOU MEANT TO JUST IMPLY THAT?

[lethal osprey]

then what dont you understand about hte equation

[vagrant wadi]

OR IS CAN YOU EQUATE FOR IT?

once ur at the point where 2^x=1

[vagrant wadi]

do you just apply this

or can you equate for it?

[lethal osprey]

yeah

what else are you supposed to do

[vagrant wadi]

thats why i was confused

and how is x also 2

[lethal osprey]

for what?

[vagrant wadi]

you said in the equation 2^x-1=0 / x can be 0 and 2

[lethal osprey]

no

for the other equation the answer came 2

2^x = 4

[vagrant wadi]

my answers say that this is true

wait what on fucks lord

i just realised

[lethal osprey]

there is only 1 answer for 1 equation

wtf

bruhh

[vagrant wadi]

wtf

[lethal osprey]

omg

u gotta sleep man

[vagrant wadi]

yea ill just ask my math teacher tmr

[lethal osprey]

head to sleep fr

[vagrant wadi]

yea ik

i need my daily 7 hrs

even tho im suppsoed to get 8+

[lethal osprey]

when i was in 9th grade

[vagrant wadi]

sleep deprived asf

[lethal osprey]

i used to sleep like 13hrs

[vagrant wadi]

DANGGGGGGGGGGGGGGGGGGG

WWWWW

[lethal osprey]

cuz it was lockdown lmao

[vagrant wadi]

HOW

[lethal osprey]

hehhehe

[vagrant wadi]

💀

lucky mf

[lethal osprey]

fr

[vagrant wadi]

TY FOR ALL YOUR HELP THO

TYSM

[lethal osprey]

i literally failed in my civics cuz i used to do math all the time

welcome!

[vagrant wadi]

DAM

ID LITERALLY PAY FOR U TO TUTOR ME

TYSM

GN

[lethal osprey]

lmao

it would be so better if we could talk

it would be easier and faster

[vagrant wadi]

my whole family has covid soo lucky me if i get to stay home

[lethal osprey]

wth

now?

[vagrant wadi]

last week of school for me until summer holidays

[lethal osprey]

covid now?

[vagrant wadi]

and i get go back to the land of ching chongs

[lethal osprey]

china?

[vagrant wadi]

my dad got covid somehow

[lethal osprey]

LMFAO

[vagrant wadi]

and spread to my brother

my mum might be fine lol

they aint sick

just have it

[lethal osprey]

same here

i had it too

[vagrant wadi]

once holidays come yes

same

[lethal osprey]

my entire family

but nothing serious

[vagrant wadi]

but mine was shit cuz i got covid while flu

[lethal osprey]

double impounder

lol

[vagrant wadi]

the grim reaper probably visited me a few times back then

LOL

gn, can i dm u for any help if i need>

[lethal osprey]

sure

would be better if we hop on a call

my fingers are tired

[vagrant wadi]

yea

[vagrant wadi]

my fingers have 8 packs

lol

[lethal osprey]

mine have 3

as every one does

[vagrant wadi]

idk i jsut never get tired of typing

[lethal osprey]

lol

i dont really get tired

i get bored

which makes me tired smh
