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

In any group, verify directly from the axioms that

(a) inverse of the inverse of x= x

(b) (xy)^inverse = (inverse y)(inverse x) for all x,y in G. (note the reversal here)

3. The attempt at a solution

(a) I tried to use the axiom that xe=x=ex but I don't know where to go from there.

(b) I don't know how to start it.
