Write your mom on your response sheet. This to a closed book and notes quiz. Explain your answers in as much detail as possible. Check your examples and results. You need to explain every step of your logic, development and calculation. No credit will be given without the intermediate steps or the explanations. Please read both questions before you start your answers. For any square nonsingular matrix M, let us denote by M^-T the inverse transpose, i.e., M^-T = (M^-1)^T = (M^T)^-1. Given any pair of (square nonsingular) matrices A and B, prove that (AB)^-T = A^-T B^-T. Let A = |1 2 2 1| Compute A^-1.
