You want to get x alone on one side. How can you do that? :)

- anonymous

i can do that by subtracting i think @Babynini

- Babynini

hm no because x is not added to 44. it's multiplied.

oh sorry i struggle a lot at math.

- Babynini

it's ok! me too lol. So since it's multiplied, we're going to divide.

- Babynini

divide both sides by 44
x=432/44

- Babynini

(we got rid of the 44 on the left side by dividing it by 44!)

- anonymous

lol and okay what are we multiplying?

- anonymous

oh okay

- Babynini

so what does that equal?

- anonymous

i got on my calculator 9.8 idk how.

- Babynini

That's exactly correct :) good job!!

- anonymous

oh really thanks!

- anonymous

now what do i do?

- Babynini

so you just simplified the right side.
and now your equation looks like this
x=9.8
that's your answer :) (Do they ask for it in decimal or fraction form?)

If (4^4)x = 4^32, what is the value of x? im very sorry i wrote the equation wrong.

- anonymous

@Babynini

- Babynini

is this a different question?

- anonymous

yes

- Babynini

ok :)
first calculate 4^4

- Babynini

do you know how?

- anonymous

no

- Babynini

ok.
\[4^4\] = 4 * 4 * 4 *4

- Babynini

because it's 4, 4 times. so what does
4 * 4* 4*4 = ?

- anonymous

it equals 16

- anonymous

hello @Babynini

- Babynini

no, that's 4 *4

- anonymous

oh

- Babynini

(sorry, working on my own math too :))
so here we have
4*4 = 16
16*4= ?

- anonymous

oh im sorry if im disturbing you and is it 16X4 or 16 to the 4 power?

- Babynini

no you're all good
16 x 4

- anonymous

its 64

- Babynini

ok, let me try to explain this better sweetie.
\[4^4= 4x4x4x4\]
so first we take
4x4 = 16
then we take that answer and multiply it by 4
16x4 = 64
then we still have to multiply it by 4 one more time because we've only done it 3 times.
64 x 4 = ?

- anonymous

it equals 256

- Babynini

perfect, and that's your answer for 4^4 because now you've multiplied 4 four times. make sense?

- Babynini

(4^4)x = 4^32
now we have
256x=4^32

- anonymous

thank you so much and again im sorry for disturbing you from your own math homework. have a nice day/night

- Babynini

wait! this stil has to be simplified more :)

- Babynini

want to finish solving it?

- anonymous

oh sorry i didnt know and yes please

- Babynini

it's ok.
so 256x=4^32

- Babynini

now doing 4^32 would be a pain without a calculator. do you have a scientific calc?

- anonymous

no i do not :/

- Babynini

hrm ok, that's fine :)

- anonymous

ok

- Babynini

let's see what we can do then, give me a moment :)

- anonymous

ok

- Babynini

let's try getting x on one side by itself first then actually.
so
(4^4)x=4^32
we just did this, how do we get x by itself?

- anonymous

dividing

- anonymous

you have to divide both sides

- Babynini

perfect!

- Babynini

so we have
\[x=\frac{ 4^{32} }{ 4^4 }\]

- anonymous

ok

- Babynini

that can be simplified more but i'm not sure how :/

- anonymous

oh i understand now

- anonymous

i get now

- Babynini

ok!

- anonymous

thanks for all your help and again sorry for interrupting you from your own math homework.

- anonymous

bye see ya

- Babynini

no it's all good :)
