WebMath Algebra Let A be a nonsingular n × n matrix. Use mathematical induction to prove that Am is nonsingular and (Am)−1 = (A−1)m for m = 1, 2, 3, . . . . Let A be a nonsingular … WebProve that, if A, B and C are three invertible n n matrices, then (ABC) 1 = C 1B 1A 1. Then use mathematical induction to extend the rule for inverting any product BC in order to nd the inverse of the product A 1A 2 A k of any nite chain of invertible n n matrices. Theorem Suppose that A is an invertible n n matrix. Then the inverse (A>) 1 of ...
