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=[[1,2,1],[3,2,1]] and B=[[3,1],[1,1],[2,1]]

If A^(-1) = [[2,1] , [1,1]] then A=

The value of |[2,1,1 ],[1,2,1],[1, 1, 2]|=

If A^(-1)=([2,1],[1,1]) ,then A is equal to: (A) ([2,-1],[-1,1]) (B) ([-2,1],[-1,-1]) (C) ([1,-1],[-1,2]) (D) ([-2,1],[1,1])

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]]

Compute the indicated products: [[2,1],[3,2],[-1,1]][[1,0,1],[-1,2,1]]

solve for x, [[x^2,1],[2,x]] + [[2x,2],[-1,2]] = [[-1,3],[1,1]]

Find the rank of A=[[1,2,-1,2],[2,2,-1,1],[-1,-1,1,-1],[2,1,-1,2]]

If A=[[2,1],[1,1]] and A^(-1)=[[1,-1],[x,2]] then x=
