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

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

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

If A=[[1,0(1)/(2),1]], then A^(100) 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,-2,1),(2,1,3)] and B=[(2,1),(3,2),(1,1)] then (AB)' 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=[(-1,3),(2,1)] then 1+A+A^(2)+…………..+oo is equal to
