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 A=[(1,0,1),(0,1,2),(0,0,4)] , show that |3A|=27|A|

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

Evalute the determinants in queations 1 and 2 : If A=|{:(1,0,1),(0,1,2),(0,0,4):}|
