If `A=[[-1,2],[0,1]]` then find `A'+A`

If A=[[-1,0],[4,2],[0,-1]] then find (-7) A.

1.If A=[[2,0,1],[-1,1,5]] and B=[[-1,1,0],[0,1,-2]] then find (AB')' .

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

If A=[[1,3,2],[-1,2,0],[0,-1,1]] , then find a matrix X such that A^(2)-2A-X=0

If A'=[[-2,3],[1,2]] and B=[[-1,0],[1,2]] then find the value of (A+2B)'

If A=[[-2,3],[1,2]] and B=[[-1,0],[1,2]] then find the value of (A+2B)

If A = [(2,0,1),(-1,1,5)] and B = [(-1,1,0),(0,1,-2)] then find AB'

If A=[(1,0),(1/2,1)] then find the value of A^50

If x+y=[[1,4,3] , [-2,5,6] , [7,0,2]] and x-y=[[3,2,5] , [4,1,2] , [1,0,4]] then find x and y

If A=[[2,3,4],[1,-1,0],[0,1,2]] , find A^(-1) . Hence, solve the system of equations x-y=3, 2x+3y+4z=17, y+2z=7
