If $$A=\begin{bmatrix} 2 & 1 & -1 \\ 0 & 1 & 4 \\ 0 & 0 & 3 \end{bmatrix}$$, then $$tr(adj(adj\ A))$$ is equal  to

Let $$A =[a_{ij}]$$ be a $$3 \times 3 $$ matrix whose determinant is $$5$$. Then the determinant of the matrix $$B = [ 2^{i-j} a_{ij} ]$$ is

$$A=\begin{bmatrix} 1 & 1 \\ 3 & 4 \end{bmatrix}$$ and A (adj A)=KI, then the value of 'K' is ...

If $$\left[ \begin{matrix} 1 & 2 & 3 \\ 2 & 3 & 1 \\ 3 & 1 & 2 \end{matrix} \right]$$ then $$|adj\ (adj\ A)|$$ is equal to

If $$A=\begin{bmatrix} 1 & -2 & 2 \\ 0 & 2 & -3 \\ 3 & -2 & 4 \end{bmatrix}$$, then $$A.adj(a)=$$

If $$A$$ is a square matrix of order $$n$$ and $$|A|=D$$ and $$|adj A|=D^{\prime}$$, then

If the points (k, 2 - 2k) (1 - k, 2k) and (-k -4, 6 -2x) be collinear the possible values of k are

If $$A = \begin{bmatrix} 4 & 2 \\ 3 & 4 \end{bmatrix}$$ then |adj A| is equal to 

If $$A = \begin{bmatrix}1 & 2 & -1\\ -1 & 2 & 2\\ 2 & -1 & 1\end{bmatrix}$$, then $$:|adj (adj.A)|=$$
