Question

If (44)x = 432, what is the value of x?

4
7
8
28

Answer 1

@Michele_Laino

Answer 2

I think its 8

Answer 3

divide 432 by 44

Answer 4

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

Answer 5

and no the answer isn't a whole numb.

Answer 6

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

Answer 7

to*

Answer 8

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

Answer 9

So A

Answer 10

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

Answer 11

Yea

Answer 12

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

Answer 13

I think its B

Answer 14

why ???

Answer 15

Nnesha, that is the question ?

Answer 16

Yea it is

Answer 17

yeah i guess^

Answer 18

what exponent rule you should apply ?

Answer 20

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

Answer 21

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

Answer 22

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

Answer 23

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

Answer 26

8

Answer 27

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

Answer 28

8 ?

Answer 29

Im thinking

Answer 30

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)

Answer 31

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

i posted the wrong one facepalm >.<

Answer 33

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

Answer 34

Im so confused the answer is B right??

Answer 35

\(\color{blue}{\text{Originally Posted by}}\) @Nnesha
\[\huge\rm x^m \times x^n = x^{m \times n}\]
m=4
n=x
m times n = 32

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

\[(4^4)^x =4^32 \]

Answer 36

4^{32}**

Answer 37

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 ?

Answer 38

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

Answer 39

Wow thats not even an answer choice thats the wrong answer

Answer 40

huh?? which one ??

Answer 41

If (44)x = 432, what is the value of x?

4
7
8
28

Answer 42

That question

Answer 43

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

Answer 44

What is the answer to this question

Answer 45

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

Answer 46

4 times what =32 ?

Answer 47

is the answer 8

Answer 48

yeah i got the same answer
4 times 8 =32
