If `A=[0]` , then `A` is

Let A=[(a,0, 0),( 0,a,0),( 0, 0,a)] , then A^n is equal to [(a^n,0, 0),( 0,a^n,0),(0, 0,a)] (b) [(a^n,0 ,0),( 0,a,0 ),(0, 0,a)] (c) [(a^n,0, 0),( 0,a^n,0),( 0, 0,a^n)] (d) [(n a,0, 0),( 0,n a,0 ),(0, 0,n a)]

If A = [{:( 0,0,0),(0,0,0) ,(0,1,0):}] ,then A is

If A=[[2,0,0],[0,2,0],[0,0,2]] ,then A^(5) is

Let {:A=[(a,0,0),(0,a,0),(0,0,a)]:} , then A^n is equal to

If A=[[0,-1,0],[1,0,0],[0,0,-1]] , then A^(-1) is

If A=[(1,-1,0),(1,0,0),(0,0,-1)] , then A^(-1) is

If A=[[a, 0, 0], [0, a, 0], [0, 0, a]] , then |A||adjA|=

If A=[[a, 0, 0], [0, a, 0], [0, 0, a]] , then |adjA|=
