[[1],[-4],[3]][[-1,2,1]]

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

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

If A=[[-1,1,1],[2,3,0],[1,-3,1]],B=[[2,1,4],[3,0,2],[1,2,1]] State whether AB=BA ? Justify your answer.

Evaluate the following : {[[1,3],[-1,-4]]+[[3,-2],[-1,1]]}[[1,3,5],[2,4,6]]

If [[9,-1,4],[-2,1,3]]=A+[[1,2,-1],[0,4,9]] then find the matrix A.

If A = [(2,2,1), (1,3,1), (1,2,2)] then A^-1+(A-5I) (AI)^2 = (i) 1/ 5 [[4,2, -1], [-1,3,1], [-1,2,4]] (ii) 1/5 [[4, -2, -1], [-1, 3, -1], [-1, -2,4]] (iii) 1/3 [[4,2, -1], [-1,3,1], [-1,2,4]] (iv) 1/3 [[4, -2, -1], [-1,3, -1], [-1, -2,4]]

A=[[1],[-4],[3]] and B =[ -1 2 1 ] then (AB)^T=

Find products : [[1,3],[1,4]][[1,2],[3,4]]

The sum of the eigen values of the matrix A=[[2,-1,3],[1,4,2],[3,1,1]] is
