ધારો કે $A = \begin{bmatrix} 0 & 0 & -1 \\ 0 & -1 & 0 \\ -1 & 0 & 0 \end{bmatrix}$ અને $B = \begin{bmatrix} 0 & 1 & 0 \\ 1 & 0 & 0 \\ 0 & 0 & 1 \end{bmatrix}$. તો $(A^{-1}B)^{-1} + (AB^{-1})^{-1}$ ની કિંમત શોધો.

  • A
    $\begin{bmatrix} 1 & 0 & 0 \\ 0 & -2 & 0 \\ 0 & 0 & 2 \end{bmatrix}$
  • B
    $\begin{bmatrix} 0 & -2 & 0 \\ 0 & 0 & -2 \\ -2 & 0 & 0 \end{bmatrix}$
  • C
    $\begin{bmatrix} -2 & 0 & 0 \\ 0 & 0 & -2 \\ 0 & -2 & 0 \end{bmatrix}$
  • D
    $\begin{bmatrix} 0 & 0 & -2 \\ -2 & 0 & 0 \\ 0 & -2 & 0 \end{bmatrix}$
