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

If A=|[1,0,1],[0,1,2],[0,0,4]| then |3A|

If A=[[1,0,0],[0,1,0],[0,0,1]] then value of |A+A'| is 1)2 2)8 3)4 4)0

If A=[[1,0,0],[0,1,1],[0,-2,4]] and 6A^(-1)=A^2+cA+dI . Then c+d is

If [[1,0,0],[0,2,0],[3,0,-1]] and A^20 +alphaA^19+betaA=[[1,0,0],[0,4,0],[0,0,1]] Find the value of (alpha+beta)

If A=[[1,0],[0,1]],B=[[1,0],[0,-1]] and C=[[0,1],[1,0]] then show that A^(2)=B^(2)=C^(2)

If A=[[1,0,0],[0,1,0],[a,b,-1]] , find A^2

Find the rank of B= [[1,0,1,1],[0,0,1,2],[0,1,0,0],[0,0,0,1]]

If A = [ [ 0 , 1 ] , [ 0 , 1 ] ] ,then A^2 is equal to ( a ) [ [ 0 , 1 ] , [ 1 , 0 ] ] ( b ) [ [ 1 , 0 ] , [ 1 , 0 ] ] ( c ) [ [ 0 , 1 ] , [ 0 , 1 ] ] ( d ) [ [ 1 , 0 ] , [ 0 , 1 ] ]

If A=[[1,2,3],[0,1,0],[1,1,0]] and B=[[-1,1,0],[0,-1,1],[2,3,4]] show that AB!=BA
