1. Let A and B be unequal diagonal matrices of the same dimension. (A diagonal matrix is a square matrix in which each entry not on the main diagonal is zero.) Determine the products AB for several pairs of such matrices. Make a conjecture about a rule that can be used to calculate AB without using row-by-column multiplication.
2. Let i = ˆš-a and let
