simple(?) exponentiation simplification

I'm beginning with
sage. It sure looks great but I still have to understand what is the actual meaning of what I type in :-(
This is where I am currently stuck:
sage: simplify( (a/b)^c - (a^c)/(b^c) ) -a^c/b^c + (a/b)^c
I would have loved to get a nice clean $0$.
What do I need to tell
sage so that it sees that $(a/b)^c$ and $a^c/b^c$ are the same?
