Are these two matrices multiplicative of each other? Why? A = [ 5 3 B = (1/2)[ -6 -3 10 6 -10 5

OpenStudy (anonymous):

what do you mean by multiplicative of each other. You mean inverse of each other?

OpenStudy (anonymous):

No, the first matrix is a singular matrix, thus it has no inverse. And therefor, the second matrix can not be the inverse of the first matrix
