Answer 1

\[2^{3(6+3x)}=2^2\]

Answer 2

set exponents equal to each other

Answer 3

and then what? I need to solve the equation

Answer 4

right!

Answer 5

after you have the exponents equal
you distribute the 3 to (stuff)

Answer 6

\[18+9x=2\]

Answer 7

8^(6+3x)=4
So now divide by 4
2^(6+3x)=1
Then take logs of both sides, if i remember correctly.

Answer 8

\[9x=2-18 => 9x=-16 => x=-\frac{16}{9}\]
