Unformatted text preview: C is equal to AB, C is also invertible. Therefore, as the product of two invertible matrices, A is invertible. 4. Solve the equation AB=BC for A, assuming that A, B, and C are square and B is invertible. AB = BC (AB)B 1 = (BC)B 1 A(BB 1) = BCB 1 AI = BCB 1 A = BCB 1 5. Answer true or false to the following a. True b. True c. False, {[2, 0, 0, 0]}, {[1, 0, 0, 0]} d. False, {[2, 0, 0, 0]}, {[1, 0, 0, 0]} e. False. If v1...
