(log(sub 2) x)^3 - log(sub 2)(2x^3)=(log(sub 2))^2-log(sub 2)(x^2) - log(sub 2)(2)

you tell us, does it look like what your text says it should look like?

anyway, simplify the logarithms first.

you have: ............(any questions about changing the logarithms?)

now let be , so you really want to solve:

can you solve that?

when done, just replace with and solve for
