Problems 23 through 26 introduce the idea-developed morefully in the next section of a multiplicative inverse of a squarematrix.23. Let2АB ==A-[39]- *-[23]2]. = [a b].¹ = [1 2].andFind B so that AB = I= BA as follows: First equate en-tries on the two sides of the equation AB = I. Then solvethe resulting four equations for a, b, c, and d. Finallyverify that BA = I as well.

23. Let a A = [3 2]. B=[ª b]. d and ¹= [1 2]. Find B so that AB = I= BA as follows: First equate en- tries on the two sides of the equation AB = I. Then solve the resulting four equations for a, b, c, and d. Finally verify that BA = I as well.
