Recall that two n xn matrices A and B are similar if there is an invertible matrix P such that P-'AP = B. Based on this definition of similarity, (a) show that if A and B are similar, then det A = det B. (Hint: Recall properties of determinants). (b) show that if A and B are similar, then A? and B² are also similar.
