If A=`[[0,2],[0,0]]` then find `A^3`

If A=[[0.8,0.6-0.6,8.0]] then find A^(3)

If A=[[0,-1],[0,2]] and B=[[3,5],[0,0]], then find A.B and B.A

If A=[[1,4],[2,3]] , and B+A=[[0,0],[0,0]] ,then find the value of B .

If A=[[3,0,0],[0,3,0],[0,0,3]] ,then find A'

If A=[[3,0,0],[0,3,0],[0,0,3]] , then find A^(4)

If A= [[3, 0, 0], [0 ,3, 0], [0 ,0, 3]] then find 4 A .

If A=[[1],[2],[3]]" and "B=[[-5,4,0],[0,2,-1],[1,-3,2]] , then find BA

" 5."[" If "A=[[3,4,2],[1,0,6]]" and "B=[[2,3,0],[1,0,4]]],[" then find "3A-2B]

If A=[[2,1,3],[4,1,0]] and B=[[1,-1],[0,2],[5,0]] find AB and BA.

If A=[{:(2,-1),(-1,2):}] , verify A^(2)-4A+3I=0 , where I=[{:(1,0),(0,1):}] and O=[{:(0,0),(0,0):}] . Hence find A^(-1) .
