Homework Statement
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)
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.
