Question

Is my work correct?

Answer 1

\[4^{-2x}*4^{x}= 64 \]

Answer 2

x = -3

Answer 3

\[2^{x}*\frac{ 1 }{ 32 }=32\]

Answer 4

x=10

Answer 5

\[64 * 16^{-3x}=16^{3x-2}\]

This on I'm confused on. x=0?

Answer 6

Correct for both.

Answer 7

Last one I will show you.

Answer 8

\[4^3\times (4^2)^{-3x}=(4^2)^{3x-2}\]
\[4^3\times 4^{(2)(-3x)}=4^{2(3x-2)}\]

Answer 9

\[4^{3-6x}=4^{6x-4}\]
\[3-6x=6x-4\]
\[12x=7\]

Answer 10

Oh, I see what I did! I cancelled out -6x with the positive 6x. lol, thank you very much!
