Can you write [tex]\sqrt{3}^5[/tex] as [itex]3^n[/itex] for some rational, n?

I'm moving this to precalc HW forum.

also, this isn't a homework or school related question. I cant see why a warning was necessary.

You can also go the other way around, and divide out as much common terms from both sides as possible. Then see if you can prove the remaining identity.
