an element of a finite group

I need help with this theorum, please.

How is this (the attachment) true? It's for my cryptology class.

You might try applying Lagrange's theorem; that should set you in the right direction.

If [itex] G [/itex] is a finite group with order [itex] |G| [/itex] then for each element [itex] a \in G [/itex] , [itex] a^{|G]} = I [/itex], the identity.

Are you asking how to write a proof of the theorem or for some intuitive indication why it is true?

LaGrange's theory helped thanks. Also, the rewritten form of the statement helped, so thanks both of you.
