If A is a square matrix such that A(Adj.A)=⎡⎢⎣400040004⎤⎥⎦ – InterviewSolution

1.	If A is a square matrix such that A(Adj.A)=⎡⎢⎣400040004⎤⎥⎦, then \|adj(adj.A)\|\|adj.A\| is equal to
Answer» If A is a square matrix such that $A (A d j . A) = ⎡ ⎢ ⎣ \begin{matrix} 4 & 0 & 0 0 & 4 & 0 0 & 0 & 4 \end{matrix} ⎤ ⎥ ⎦,$ then $\frac{\| a d j (a d j . A) \|}{\| a d j . A \|}$ is equal to
