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

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

If A=[[1,2],[-1,-2]] then A^2 is equal to

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

If A=[[1,0(1)/(2),1]], then A^(100) is equal to

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=[[x,0],[-1,2x]] and A^-1 =[[1,0],[1/2,1/2]] then x is equal to (i) -2 (ii)-1 (iii)1 (iv)2

If A=[[-1,(3)/(2)],[-(1)/(2),(1)/(2)]] then A^(2) is equal to

If A=[[-1, 3/2] , [-1/2, 1/2]] then I+ A+ A^2+... is equal to

If A=[(1,0),(1//2,1)] , A^(400) is equal to
