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

If A=[[1,0,1],[0,1,2],[0,0,4]] then show that |3A|=27|A|

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

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

If A=[[1 ,0 ,1],[0 ,1, 2],[ 0, 0, 4]] , then show that |3A|" "=" "27|A|

If A=[(1,0,0),(0,1,0),(3,4,-1)] and A^(n)=l , then value of n is equal to

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

If [1,x,2][[2,3,1],[0,4,2],[0,3,2]][[x],[1],[-1]]=0 , then the value of x 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)
