Take the log of both sides. Choice of base depends on whether:
1) you want an exact answer or if you have a calculating device that can give you a log value to any base you choose in which case choose base 5
2) you definitely want a numeric approximation and you only have tables or a calculating device that gives you base 10 or base e logs in which case choose base 10 or e.

Like I said, use any base you like, but if you just want to render the exact answer use base 5 because , so the expression would reduce to:
