If `A=[[8,-3,4],[1,5,-2],[3,0,1]]`, then `|A|=?`

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

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

If A=[[-5,-8,0],[3,5,0],[1,2,-1]], then transpose of A is

3.If A= [[1,2,3],[2,3,4],[3,4,5]] , then 2A'-A=_ (A) [[1,2,3],[2,3,6],[3,3,7]] (B) [[-1,0,3],[4,5,6],[7,-8,1]] (C) [[1,5,3],[-2,4,0],[5,7,8]] (D)None of these

If A=[[1, 2, 3], [3, 4, 5], [4, 6, 8]] , then

If, A=[(1,1,2),(0,-3,5),(-2,3,4)] ,then is 4A=[(4,4,8),(0,-12,20),(-8,12,16)] ?

Find the rank of A=[[8,1,3,6],[0,3,2,2],[8,-1,-3,-4]]

If the matrix A=[[1,2,3,0],[2,4,3,2],[3,2,1,3],[6,8,7,alpha]] is of rank 3 then alpha= (A) -5 (B) 5 (C) 4 (D) -4
