Let A and B be square matrices of order 3 such that A 6 and B 9 a Find ABI b Find 2A c Are A and B singular or nonsingular Explain O A and B are both singular because they both have nonzero determinants O A and B are both nonsingular because they both have nonzero determinants OA is singular but B is nonsingular because A B OB is singular but A is nonsingular because A BI d If A and B are nonsingular find A1 and B 1 If the inverse is undefined enter UNDEFINED A 1 B e Find AB 1
