If `A=[[1,1],[0,1]]`, then `A``A'=?`

If [[1, 1], [0, 1]]A=I , then A=

If A=[[1,0,1],[0,1,1],[1,0,0]] then A^-1 is

If A=[[1,0,1],[0,1,1],[1,0,0]], then |A| is

If A=[[1,1] , [0,1]] and B=[[1,-1] , [0,1]] then AB=

If A=[[1,1,1],[1,2,1],[1,1,2]] ,then prove that A^(-1)=[[3,-1,-1],[-1,1,0],[-1,0,1]]

If [[1,3],[0,1]]A=[[1,1],[0,-1]] then the value of A is

If [[1,3] , [0,1]] A = [[1,1] , [0,-1]] then find the value of A

If [[2, 1],[ 3, 2]]A[[-3 ,2],[ 5,-3]]=[[1 ,0],[ 0, 1]], then "A= (A) [[1, 1],[ 1 ,0]] (B) [[1, 1],[ 0, 1]] (C) [[1 ,0],[ 1 ,1]] (D) -[[1, 1],[ 1, 0]]

Let {:[(1,2),(0,1):}][{:(1,2),(0,1):}]......[{:(1,n-1),(0,1):}]=[{:(1,78),(0,1):}] If A=[{:(1,n),(0,1):}] then A^(-1)=
