I need some help from some of the algebraists on the board.
I have the following problem... I have tried so many ways to prove it but I just can't seem to get there.
The Problem is:
Let G be a group with a,b in G. Prove that b and aba^(-1) have the same order.
I have attempted to show for finite order and infinite order, but no matter what i do I can't see it... Any help would be greatly appreciated...
Thanks!!!
