1.	Let A be a 3×3 matrix such that adjA=⎡⎢⎣2−11−1021−2−1⎤⎥⎦ and B=adj(adjA).If \|A\|=λ and ∣∣(B−1)T∣∣=μ, then the ordered pair, (\|λ\|,μ) is equal to:
Answer» Let $A$ be a $3 \times 3$ matrix such that $a d j A = ⎡ ⎢ ⎣ \begin{matrix} 2 & - 1 & 1 - 1 & 0 & 2 1 & - 2 & - 1 \end{matrix} ⎤ ⎥ ⎦$ and $B = a d j (a d j A)$ . If $\| A \| = λ$ and $∣ ∣ {(B^{- 1})}^{T} ∣ ∣ = μ$ , then the ordered pair, $(\| λ \|, μ)$ is equal to:
