Trying to solve the following: Let G be a group with a finite number
of elements. SHoe that for any a belonging to G, there exists n
belonging to the positive integers such that a^n=e (identity
element). [Hint: consider e,a,a^2, a^3.....a^m where m is the number
of elements in G , and use the cancelation laws.]

Any suggestions welsome, this is a new subject to me.
