If matrix `A=[1-1-1 1]` and `A^2=k A ,` then write the value of `kdot`

If matrix A=[[1,-1-1,1]] and A^(2)=kA then write the value of k and A^(2)=kA

8.If A is a square matrix of order 3 and |3A|=k1A1, then write the value of k.

If k-1,k+1 and 2k+3 are in AP , then the value of k is

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

If [(1, 2),( 3, 4)][(3, 1),( 2, 5)]=[(7, 11),( 23, k)] , then write the value of kdot

If the rank of the matrix [[-1,2,5],[2,-4,a-4],[1,-2,a+1]] is 1 then the value of a is (A) -1 (B) 2 (C) -6 (D) 4

If [213][-10-1-110011][10-1]=A then write the order of matrix A.

If matrix A=[{:(3,2,4),(1,2,-1),(0,1,1):}]and A^(-1)=1/k adj A, then k is
