" Q.31.If "A^(-1)=[[3,-1,1],[-15,6,-5],[5,-2,2]]" and "B=[[1,2,-2],[-1,3,0],[0,-2,1]]," find "(AB)^(-1)

If A^(-1)=[{:(3,-1,1),(-15,6,-5),(5,-2,2):}] and B=[{:(1,2,-2),(-1,3,0),(0,-2,1):}] then find (AB)^(-1)

If A^(-1)=[3-1 1-15 6-5 5-2 2] and B=[1 2-2-1 3 0 0-2 1] , find (A B)^(-1) .

If A^(-1)=[3-1 1-15 6-5 5-2 2] and B=[1 2-2-1 3 0 0-2 1] , find (A B)^(-1) .

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

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

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

If A=[[1,2,3],[-1,0,2],[1,-3,1]], B=[[4,5,6],[-1,0,1],[2,1,2]], C=[[-1,-2,1],[-1,2,3],[-1,-2,2]] find A-2B+3C. Also verify that (A+B)+C=A+(B+C).

If A=[[1,2,3],[-1,0,2],[1,-3,1]], B=[[4,5,6],[-1,0,1],[2,1,2]], C=[[-1,-2,1],[-1,2,3],[-1,-2,2]] find A-2B+3C
