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

A= [[0,1],[1,0]] and |A^(2020)| =2K then K=

If "|[1,k,3],[3,k,-2],[2,3,-1]| =0," then the value of "k" is

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

Let, C_(k) = ""^(n)C_(k) " for" 0 le kle n and A_(k) = [[C_(k-1)^(2),0],[0,C_(k)^(2)]] for k ge l and A_(1) + A_(2) + A_(3) +...+ A_(n) = [[k_(1),0],[0, k_(2)]] , then

If A=([1,0],[1,2]) and A^(8)=KA-lI then K-l =

( k - 1 ) x - y = 5 , (k + 1 ) x + ( 1 - k ) y = ( 3k + 1 )

If A=([1,0],[1,2]) and A^(8)=KA-lI then K-l

Matrix A=[[1, 0, -k], [2, 1, 3], [k, 0, 1]] is invertible for
