If `A=[[4,5,2],[2,1,1],[0,1,1]]`, then `|A|=?`

" 2.Let "A=[[1,0,2],[2,0,1],[1,1,2]]," then "(det((A-I)^(3)-4A))/(5)" is "

Q.4 If A= [[0,1,-2],[-1,0,5],[2,5,0]] , then (a)A'=A (b)A'=-A (c)A'=2A (d) None of these

If A=[[1,0,-2],[3,-1,0],[-2,1,1]],B=[[0,5,-4],[-2,1,3],[-1,0,2]] and C=[[1,5,2],[-1,1,0],[0,-1,1]] verify that A(B-C)=(AB-AC)

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

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

If A=[[1,0,5],[2,-1,3],[4,1,0]] and B=[[3,2,1],[0,2,1],[3,2,5]] .Show that (a) ( A + B )' = A' + B' (b) (2A)'=2A'

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

If A=[[1,2,3],[0,-1,4],[3,1,5]] and B=[[2,-1,0],[1,4,3],[3,0,-2]], verify that (AB)^-1=B^-1A^-1.

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

If A=[[1,2,-3] , [5,0,2] , [1,-1,1]] and B=[[3,-1,2] , [4,2,5] , [2,0,3]] then find matrix C such that A+2C=B
