Verify that (AB)' = B 'A ' in `A=[[1,2,1],[3,2,1]]` and `B=[[3,1],[1,1],[2,1]]`

Verify that (AB)' = B 'A ' in A=[[2,1,2],[1,2,1]] and B=[[1,2],[2,1],[1,1]]

Verify that (AB)' = B 'A ' in A=[[1,2],[3,-4]] and B=[[4,3],[2,1]]

Verify that (AB)' = B 'A ' in A=[[5,2],[2,3]] and B=[[1,2],[1,4]]

Verify that (AB)' = B 'A ' in A=[[3,4],[5,4]] and B=[[5,3],[2,1]]

For the matrices A and B, verify that (AB)' = B'A' , where : A = [[1],[-4],[3]], B = [[-1,2,1]]

If A = [[1,2,3],[2,3,1]] and B = [[3,-1,3],[-1,0,2]] , then find 2A – B.

If A = [[-1,2,3],[5,7,9],[-2,1,1]] and B = [[-4,1,-5],[1,2,0],[1,3,1]] , then verify that (A-B)' = A' - B'

If A = [[-1,2,3],[5,7,9],[-2,1,1]] andB = [[-4,1,-5],[1,2,0],[1,3,1]] , then verify that (A+B)' = A' + B'
