If `A=[[1,1] , [0,1]]` and `B=[[1,-1] , [0,1]]` then `AB=`

If A = [[1,0],[0,-1]] and B=[[0,1],[1,0]] , then AB = [[0,1],[-1,0]] and BA = [[0,-1],[1,0]] . Clearly AB ne BA Thus matrix multiplication is not commutative.

1.If A=[[2,0,1],[-1,1,5]] and B=[[-1,1,0],[0,1,-2]] then find (AB')' .

If A=[[0,1],[1,0],[0,1]] and B=[[0,1,2],[2,1,0]], find AB

If A=[[1, 0],[ 0,-1]] and B=[[0 ,1], [1, 0]] , then find AB,BA. Show that 'A B!=B A .

If A=[[2,3],[0,1]] and B=[[3,4],[2,1]] ,then (AB)=

If A=[[2,1,3],[4,1,0]] and B=[[1,-1],[0,2],[5,0]] find AB and BA.

If A=[[2,1,3],[4,1,0]] and B=[[1,-1],[0,2],[5,0]] find AB and BA.

Let A=[[2,1,3],[4,1,0]] and B=[[1,-1],[0,2],[5,0]] Find AB

If A=[[2,1,3],[4,1,0]] and B=[[1,-1],[0,2],[5,0]] , verify that (AB)\'=B\'A\'

If A=[[1,1],[0,1]],B=[[0,1],[1,0]] then AB=
