P2. (8pts) Finish computing the optimal way to multiply matrices A, through As, where their dimensions are as follows (You can assume that the array index begins at 1). AT: 7 5 : : 9 2 Az: 5 x 10 Ag! 10 x9 A.: 9x2 As: 2 3 M 1 2 3 4 5 1 0 350 350 0 765 450 OWN 0 180 0 310 240 54 0 5 What are the values of M[2][4], M[1][5], P 2][), and P[1][5]
