Two matrices whose product is the multiplicative identity
Chapter 7, Problem 7.1.185(choose chapter or problem)
Two matrices whose product is the multiplicative identity matrix are said to be multiplicative inverses. That is, if A * B = B * A = I, where I is the multiplicative identity matrix, then A and B are multiplicative inverses. In Exercises 69 and 70, determine whether A and B are multiplicative inverses.A = c 5 -2 -2 1 d , B = c 1 2 2 5 d
