If `A=[[1,2],[2,1]]` and `A(adj A)=kI` then the value of k is.....

If A=[[1,2],[2,1]] and A(adjA)=k , then the value of k is

If A=[[3,2],[1,4]], then A(adj A)=

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

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

If A=[{:(,1,2),(,2,1):}] then adj A=

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

" If "A=[[1,-1,1],[0,2,-3],[2,1,0]]" and "B=(adj A)" and "C=5A" ,then find the value of "(|adj B)/(|C|)

Let A and B are square matrices of order 3. If |A|=4, |B|=6, B=A-2I and |adj(I-2A^(-1))|=k , then the value of k is equal to
