Let `A=[(a,0,0),(0,a,0),(0,0,a)]` then `A^2` is equal to

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

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=[(1,0,0),(0,1,0),(a,b,-1)]:} , then A^2 is equal to

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

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

If A =[{:(a,0,0),(0,a,0),(0,0,a):}] , then det (adjA) equals
