logic - Why I am not getting True when testing equation?

My input is:

$ \frac{1}{a^x}==(\frac{1}{a})^x $

I want to get output:

True

But getting output:

$ a^{-x}==\left(\frac{1}{a}\right)^x $

Question: How to get output: True

Answer

Your expression is only true if a is positive.

Simplify[a^-x == (1/a)^x, a > 0]

True
