Compute the indicated products.(i) [[a, b],[-b ,a]][[a,-b],[b, a]] (ii) [[1],[ 2],[ 3]][[2, 3 ,4]] (iii) [[1,-2],[ 2 ,3]] [[1 ,2, 3],[ 2, 3 ,1]] (iv) [[2, 3 ,4 ],[3, 4 ,5],[ 4, 5, 6]][[1,-3, 5],[ 0, 2, 4],[ 3, 0, 5]] (v) [[2,1],[3,2],[-1,1]] [[1, 0, 1],[-1, 2 ,1]] (vi) [[3,-1, 3],[1,0,2]] [[2 ,-3],[ 1, 0],[ 3, 1]]

If A = [[-1, 2 ,3],[-1, 0, 2],[1, -3, 1]] and B = [[4,5,6],[-1, 0, 1], [2,1,2]], find 4A-3B

If A=[[1,2,-3] , [5,0,2] , [1,-1,1]] and B=[[3,-1,2] , [4,2,5] , [2,0,3]] then find matrix C such that A+2C=B

If A = { 1,2,3,4 }, B = { 2, 4, 5,6 } , U = { 1,2,3,4,5,6,7} then A' ∩ B'

If A=[[2,-1,5] , [4,0,3]] and B=[[-2,3,1] , [-1,2,-3]] then find A'+B'

If A=[[1,2,5],[3,4,6]] and B=[[4,0],[2,1]] , then find AB.

If A=[[2,5,6] , [0,1,2]], B =[[6,1] , [0,4] , [5,7]] then verify that (AB)'=B'A'
