Find A if [[1,0,-1],[-2,-1,4],[-1,0,2]]A = [[-1,-2,2],[3,4,-3],[3,4,-1]]

A=[[1,2,3],[3,-2,1],[4,2,1]] A^-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]]

Find the rank of matrix [ [1,1,-3,2],[2,-1,2,-3],[3,-2,1,-4],[-4,1,-3,1] ]

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

If A = [[1, 1, 3], [1, 3, -3], [-2, -4, -4]] , then A^(-1) is

If A=[(1,1,1),(2,4,1),(2,3,1)],B=[(2,3),(3,4)] then the matrix BA is

If A=[[1, 2, 3], [1, 3, 4], [3, 4, 3]] , then |A^(-1)|=

Compute the indicated products : (1) [{:(3,-1,4),(2,3,1):}][{:(1,3,4),(2,1,0),(-3,2,3):}] (2) [{:(1,3),(2,1):}][{:(4),(-1):}] (3) [{:(1,4,2),(5,-2,3):}][{:(2,-4),(1,-3),(4,0):}] (4) [1" "2," "3][{:(2),(4),(6):}] (5) [{:(2),(4),(6):}][1" "2," "3]

If A=([1,2,3],[1,3,4],[1,4,3]), then | adj A| =
