(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

G and H are isomorphic.

Prove that if x^{-1}=x for all x in G, then x^{-1}=x for all x in H.

2. Relevant equations

G is isomorphic to H means there is an operation preserving bijection from G to H.

3. The attempt at a solution

I need a point in the right direction.
