If `A=[i0 0i]` , write `A^2` .

If A=[[i,0], [0,i]] , write A^2 .

If A=[(i,0),(0,i)] , find A^(2) .

If A=[(i,0),(0,-i)] , then A A'=

If A=[(0,-i),(-i,0)] then A^(2)=

If A=[(i,0),(0,i)] then find A^(2) .

If A=[(i,0), (0,i)],\ n in N , then A^(4n) equals [(0,i), (i,0)] (b) [(0 ,0) ,(0, 0)] (c) [(1, 0) ,(0, 1)] (d) [(0,i) ,(i,0)]

If A = [(-i,0),(0,i)] then A ' A is equal to
