1. The problem statement, all variables and given/known data My textbook has no answers so I was wondering if someone could let me know if I'm right. The question: A and B are m x n matrices. Let A = I. Find when B = A. 2. Relevant equations 3. The attempt at a solution What I did seems too easy: If B ~ A, then A ~ B (this is just a property of similarity) Since A = I, we can sub in for A So B = A Did I just argue myself in circles?
