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

2) If A=[(1,2),(2,1)] and A(AdjA)=K.I then the value of K is

If A={:[(1,2),(3,4)]:}," then: " adj(adjA)=

Select the correct option from the given alternatives. If A=[[2,-4],[3,1]] and A(adj A)=KI then the value of k is….. i] 1 ii] -1 iii] 0 iv] 14

If A={:[(4,2),(3,4)],:}" then: "|adj,A|=

If A={:[(4,2),(3,4)],:}" then: "|adj,A|=

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