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

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

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

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

If A=[(1,-1),(-1,1)] and A^(2)=lamdaA , then the value of lamda is :

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

if A=[[1,1,1],[1,1,1],[1,1,1]] then find A^2

Consider the following in respect of the matrix A=({:(-1,1),(1,-1):}) : 1. A^(2)=-A 2. A^(3)=4A Which of the above is/are correct ?
