(you make apply b^(-1) since b = b^(-1)

I am learning about Group Theory now and is in subgroup session. However, the problem does not say x = b^(-1)

This is a WAY different question than what you originally asked. It's asking you to prove that if b is the only element of order 2, then it commutes with every element of G.

Let and consider . What is the order of this element? What does that tell you about its relation to the element b?
