(adsbygoogle = window.adsbygoogle || []).push({}); math help please!!

here is the question i am having trouble with.

5^(log(3X) – log(3)2) = 125...where the base is in brackets.

This is how i attempted to solve for x, but i got stuck. Can someone please help me out. thanks

I understand u can make the 125=5^3 and then:

log(3X) - log(3)2 = 3

log(3X) = 3 + [(log2)/(log3)]

log(3X) = 3.63

Now what? :uhh:

The answer in the book is 54.
