x = −2
x = −1
x = negative 1 over 4
x = negative 1 over 3

I think It's D.

Answer 1

ur right want a fan

Answer 2

are you solving for x ?

Answer 3

yes

Answer 4

nice bio berry

Answer 5

smh thx

Answer 6

Ok to solve for a variable in the exponent, you want to change both sides to having the same base. So you want a common factor between 64 and 16. Which would be? :)

Answer 7

I'm thinking D.

Answer 8

btw i read EVERYONE'S bio

Answer 9

i'd say d

Answer 10

it seems to add up more than the rest

Answer 11

Wait C.

Answer 12

4^3 = 64. I was meaning the exponent; not division :) SO it would look like this 4^3x = 4^(2x-2) Then you can set 3x=2x-2 and solve for x=-2 :) does that make sense?

Answer 13

yea I think it is c too
