Question

the solution to 64^(4-x)=4^(2x)

Answer 1

Rewrite 64 as 4^3 to get


(4^3)^(4-x) = 4^(2x)


Then multiply exponents to get


4^(3(4-x)) = 4^(2x)


Since the bases are equal, the exponents must be equal, so


3(4-x) = 2x


Solve that for x to get your answer.

Answer 2

is it x=12/5

Answer 3

you got it, nice job

Answer 4

yay! :)
