1.Let AAA be a 3×33 \times 33×3 matrix such that adj A=(2−11−1021−2−1)\text{adj}\, A = \begin{pmatrix} 2 & -1 & 1 \\ -1 & 0 & 2 \\ 1 & -2 & -1 \end{pmatrix}adjA=2−11−10−212−1 and B=adj(adj A)B = \text{adj}(\text{adj}\, A)B=adj(adjA). If ∣A∣=λ|A| = \lambda∣A∣=λ and ∣(B−1)T∣=μ\left| (B^{-1})^{T} \right| = \mu(B−1)T=μ, then the ordered pair (λ,μ)(\lambda, \mu)(λ,μ) is equal to:a.(9, 1)\left(9, \, 1\right)(9,1)b.(9, 181)\left(9, \, \dfrac{1}{81}\right)(9,811)c.(3, 1)\left(3, \, 1\right)(3,1)d.(3, 181)\left(3, \, \dfrac{1}{81}\right)(3,811)Login to continueOnly logged in users canattempt or see the solution.
