Select and write the most appropriate answer from the given alternative of the following If A = [[1,2],[3,4]] and A(adjA) = kI , then the value of k is i] 2 ii] -2 iii] 10 iv] -10

Select the correct option from the given alternatives. If A = [[1,2],[3,4]] and A(adjA) = kI then the value of k is i]2 ii]− 2 iii]10 iv]− 10

If A=[[1, 2], [3, 4]] , then A(adjA)=kI, then k=

A = {:[(1,2),(3,4)]:} and A (adj A) = kI , then the value of 'k' is

If A=[[2, -3], [4, 1]] , then adjA=

If A=[[1,2,3],[2,3,4],[0,0,2]] then the value of adj(adjA) is-

if A =[[2,3],[1,4]] then adjA = ?

If A=[(1,3),(2,-1)] then AdjA=
