If `A[[3,0,0] , [0,3,0] , [0,0,3]]` then `A^4=[[3^k,0,0] , [0,3^k,0] , [0,0,3^k]]` then `k=`

If A=[[2,3],[3,5]] and A(adj A) =[[k,0],[0,k]] then k is :

A={:[(k//2,0,0),(0,l//3,0),(0,0,m//4)]:}and A^(-1)={:[(1//2,0,0),(0,1//3,0),(0,0,1//4)]:} , then k+l+m=

If X+Y=[(5,2),(0,9)] and X-Y=[(3, 6), (0,-1)] and X=[(k,k),(0,k)] , then k =

If A(adj A) = ((7k,0,0), (0,7k,0),(0,0,7k)) then find |adjA|.

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

If A=[((k)/(2),0,0),(0,(l)/(2),0),(0,0,(m)/(4))] and A^(-1)= [((1)/(2),0,0),(0,(1)/(3),0),(0,0,(1)/(4))] then k+l+m=

If A=[((k)/(2),0,0),(0,(l)/(2),0),(0,0,(m)/(4))] and A^(-1)= [((1)/(2),0,0),(0,(1)/(3),0),(0,0,(1)/(4))] then k+l+m=

If A= [[0,2],[3,-4]], k A= [[0,3a],[2b,24]] then the value of k, a, b are respectively

If |[3,-1],[1,k]|=0 then k is equal to?

If the points (3,0),(0,4),(0,0) and (k,4) are concylic then k=
