Exercise 1.5.3. Suppose AB = BA. In previous homework, we see that this implies that A, B must have a common eigen vector. * 1. Show that we can find invertible X, such that X, AX;' = [er 1.]* ton and , XBX' BI A B = BAL. (Hint: Use the common eigenvector.) 2. Show that A, B can be simultaneously triangularized. (Hint: Look at A1, B1 and use induction.)
