Show that If N is a normal subgroup of G, a ∈ G and n ∈ N, so there is an element n' ∈ N such as an = n'a.
Can someone help me with this exercise, please? From the definition of normal subgroups, I know that aN = Na, for every a ∈ G. But I can't see how an = n'a (assuming n different from n') can happen.
