1.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[[3,0,0] , [0,3,0] , [0,0,3]] then A^4=[[3^k,0,0] , [0,3^k,0] , [0,0,3^k]] then k=

If A=[[3, 0, 0], [0, 3, 0], [0, 0, 3]] , then |A||adjA|=

If A=|[1,0,1],[0,1,2],[0,0,4]| then |3A|

If A=([3,0,0],[4,5,0],[2,1,6]) then A^(-1)=

If A = [(3,0,0),(0,3,0),(0,0,3)] , then |A||adj A| =...

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

If A=[(2,0,0),(0,2,0),(0,0,2)] , then find the value of A^(3) .

Let a be a 3xx3 matric such that [(1,2,3),(0,2,3),(0,1,1)]=[(0,0,1),(1,0,0),(0,1,0)] , then find A^(-1) .
