Reply if you get stuck on any of these:

(1) Divide by 9^(2x) and 8^(x) so you have 1 on the right hand side

(2) Simplify left hand side until you only have one power of 2 and one power of 3

(3) Split both powers so you have one with x and one without x in the exponent, do this for the power of 2 and the power of 3 separately

(4) Combine the x-powers into a power of 6

(5) Solve the equation for 6^x

(6) Square the equation so you get 6^(2x)

(7) Multiply the equation with ln(e^(-1))
