If `A=[[2,-4],[1,-2]]`, then `A^(2)` is

If A=[[0,1,3],[1,2,x],[2,3,1]] and A^(-1)=[[(1)/(2),-4,(5)/(2)],[-(1)/(2),3,-(3)/(2)],[(1)/(2),y,(1)/(2)]] . Find x,y

If A=[(3,2,-1),(4,-1,2),(0,1,2)] then adj (adjA) is

If A=[[2,-1],[4,2]],B=[[4,3],[-2,1]],C=[[-2,-3],[-1,2]] , compute the following: A+(2B-C)

If A=[[2,-1],[4,2]],B=[[4,3],[-2,1]],C=[[-2,-3],[-1,2]] , compute the following: -2A+(B+C)

If A=[[2,-1],[4,2]],B=[[4,3],[-2,1]],C=[[-2,-3],[-1,2]] , comopute the following: A+(B+C)

If A=[[2,-1],[4,2]],B=[[4,3],[-2,1]],C=[[-2,-3],[-1,2]] , compute the following: (A+B)+C

If A=[[2,3,1] , [1,3,2] , [1,2,3]], B=[[4,1,2] , [2,4,1] , [1,4,2]] verify that (A+B)^T=A^T+B^T

Find the Rank of the Matrix. [[2,3,-2,4],[3,-2,1,2],[3,2,3,4],[-2,4,0,5]]"
