if A = [2 3][1 4] and B = [ 0 -2][1 5], find AB
i got this answer the last time i posted this question and i just want to confirm that it is correct...it seems quite logical to me
A = [2 3]
......[1 4]
B = [0 -2]
......[1 .5]
? If so then the product of the two 2x2 matrices is:
AB = [2 3] [0 -2] = [(2(0) + 3(1)) (2(-2) + 3(5))]
........[1 4] [1 .5]....[(1(0) + 4(1)) (1(-2) + 4(5))]
AB = [3 11]
........[4 18] is this the final answer or do i solve this
