if A=[{:(1,-1,1),(2,1,-1),(-1,-2,2):}] then show that A^(-1) Does not exist.

if A=[{:(1,-1,1),(2,1,-1),(-1,-2,2):}] then show that A^(-1) Does not exist.

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

If A=[{:(1,-1,1),(2,1,-1),(-1,-2,2):}] show that A^(-1) does not exist.

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

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

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

The value of [[1],[1],[2]][[1,-1,2]][[2],[1],[0]] is a) [[1],[0],[0]] b) [1,1,2] c) [[1],[1],[2]] d) [[2],[1],[3]]

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])
