matrix A=({:(-i,0),(0,-i):}) then A^2 =

If A=[{:(4,1),(3,2):}] and I=[{:(1,0),(0,1):}] then A^(2)-6A is equal to : a) 3I b) -5I c) 5I d) none of these

If A=[[i,0], [0,i]] , write 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=[ (3,-2),( 4 ,-2) ] and I=[(1,0),(0,1)] , then prove that A^2-A+2I=O .

If A=[{:(,3,1),(,-1,2):}] and I=[{:(,1,0),(,0,1):}] ,find A^2-5A+7I .
