To get started see if you can generate an example vector and construct A and see what the answer is for that case. Then ask what choices you had in your example and whether any of those choices change the problem.

I'm rather confused, because ## a \cdot a'## is a number not a matrix. Where are you supposed to get A from?

aa' is a NxN matrix. It's a'a that is a scalar.
