If `A=[[3, 2], [0, 1]]`, then `(A^(-1))^(3)=`

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

If A=[[-3,1,2],[0,0,1],[-3,5,0]] ,then 8|A|

If A= [[0,-2,3],[2,0,-1],[-3,1,0]] then A^5 is

If A==[[1, -1, 3], [2, 1, 0], [3, 3, 1]] , then first 3R_3 and then C_3 to C_3 +2C_2 on A gives

If A' = [[3,4],[-1,2],[0,1]] and B = [[-1,2,3],[1,2,3]] , then verify that (A + B)' = A' + B'

If A' = [[3,4],[-1,2],[0,1]] and B = [[-1,2,3],[1,2,3]] , then verify that (A - B)' = A' - B'

If A=[[2,a,-3] , [0,2,5] , [1,1,3]] then,find the value of a for which A^(-1) exists.

If A=[[2,a,-3] , [0,2,5] , [1,1,3]] then,find the value of a for which A^(-1) exists.

If A=[[1,3,2],[2,0,-1],[1,2,3]] ,such that A satisfies the equation A^(3)-4A^(2)-3A+kI=O where k-2

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