I think its 8

- welshfella

divide 432 by 44

is that \(\large\color{black}{ \displaystyle (44)^x=432 }\) or \(\large\color{black}{ \displaystyle (44)\times x=432 }\)

- SolomonZelman

and no the answer isn't a whole numb.

- SolomonZelman

the quickest step for (44)^x is take log base 44, and use a calculator for the left side.
for (44) times x, just divide as welshfella has told you too

- SolomonZelman

to*

- Nnesha

it's \[\huge\rm (4^4)^x =4^{32}\]
right ?

- nuccioreggie

So A

- Nnesha

which one is it ? is this ur question ??\[\huge\rm (4^4)^x =4^{32}\]

- nuccioreggie

Yea

- Nnesha

alright so now YOU tell me the answer remember we did this yesterday ?

- nuccioreggie

I think its B

- Nnesha

why ???

- SolomonZelman

Nnesha, that is the question ?

- nuccioreggie

Yea it is

- Nnesha

yeah i guess^

- Nnesha

what exponent rule you should apply ?

- nuccioreggie

Ok can u do wat u did yester day wen u asked me what do i multiply to get this number,so it will be much eisier

- Nnesha

you already know ^^^
it's a same method but with different numbers

- SolomonZelman

ok... next time use an equation editor or denote an exponent using a caret, the ^ (Shift+6)

- Nnesha

\[\huge\rm x^m \times x^n = x^{m \times n}\]
m=4
n=x
m times n = 32
substitute 4 and then solve for n

8

- Nnesha

check ur answer
\[\huge\rm (4^4)^8 = 4^{ 4 \times 8} = 4^{?}\]

- nuccioreggie

8 ?

- nuccioreggie

Im thinking

- SolomonZelman

u don't accept messages, so I will say this right here.
you maid a mistake when you quoted the poster. The law of multiplying x^n times x^m gives x^(m+n)

- SolomonZelman

\(\Large\color{black}{ \displaystyle \rm x^m\times x^n=x^{m+n} }\)

i posted the wrong one facepalm >.<

- Nnesha

\[\huge\rm (x^m)^n = x^{m \times n}\]

- nuccioreggie

Im so confused the answer is B right??

i mean to post this exponent rule \[\huge\rm (x^m)^n = x^{m \times n}\]
\[(4^4)^x =4^32 \]

- Nnesha

4^{32}**

- Nnesha

check your answer \[\huge\rm (4^4)^7 = 4^{32}\]
is this right 4 times 7 =32?
\[\large\rm (4^4)^8 =4^{32}\]
both sides are equal ?? 4 times 8=32 ??
\[\huge\rm (4^4)^4 = 4^{32}\]
4 times 4 = 32 ?

- Nnesha

when you multiply both exponents you should get 32
got it ? :-)

- nuccioreggie

Wow thats not even an answer choice thats the wrong answer

- Nnesha

huh?? which one ??

- nuccioreggie

If (44)x = 432, what is the value of x?
4
7
8
28

- nuccioreggie

That question

- Nnesha

i'm saying if you u don't know exponent rules then you can substitute all answer choices for x to check your answer

- nuccioreggie

What is the answer to this question

- Nnesha

you already know
\[\huge\rm (4^4)^x =4^{32}\]
4 times x = 32
you got it right!

- Nnesha

4 times what =32 ?

- nuccioreggie

is the answer 8

- Nnesha

yeah i got the same answer
4 times 8 =32
