Show that (A¹)' = A. Let A and B be two nxn matrices. Show that a) (A + B) = A' + B¹. b) (AB) = B'A'. If A and B are nxn matrices with AB = BA = I, then B is called the inverse of A (this terminology is appropriate be- cause such a matrix B is unique) and A is said to be invertible. The notation B = A-¹ denotes that B is the inverse of A.
