1. The problem statement, all variables and given/known data Matrix A and B are both square matrices of the same size. Is it possible to compute, AB^2009 If not, why not? 3. The attempt at a solution Just had this question in an exam, the exam did not allow calculators and I could not answer this question, I gather it is not possible but I cannot explain why. Because A and B are square matrices it is possible to multiply them together but I am unsure about the exponent. Any ideas?
