જો $A = \begin{bmatrix} 0 & 1 & 2 \\ 1 & 2 & 3 \\ 3 & a & 1 \end{bmatrix}$ અને $A^{-1} = \begin{bmatrix} 1/2 & -1/2 & 1/2 \\ -4 & 3 & c \\ 5/2 & -3/2 & 1/2 \end{bmatrix}$ હોય,તો:

  • A
    $a = 1, c = -1$
  • B
    $a = 2, c = -1/2$
  • C
    $a = -1, c = 1$
  • D
    $a = 1/2, c = 1/2$

જો શ્રેણિક $A = \begin{bmatrix} 2 & 3 \\ 1 & -4 \end{bmatrix}$ નો વ્યસ્ત શ્રેણિક $A^{-1} = \begin{bmatrix} a & 3/11 \\ 1/11 & b \end{bmatrix}$ હોય, તો $a+b=$ . . . . . . .

જો $A$ એ $n \times n$ શ્રેણિક હોય,તો $adj(adj \,A) = $

ધારો કે $A$ એ $3 \times 3$ ક્રમનો શ્રેણિક છે અને $|A|=5$ છે. જો $|2 \operatorname{adj}(3 A \operatorname{adj}(2 A))|=2^\alpha \cdot 3^\beta \cdot 5^\gamma$ જ્યાં $\alpha, \beta, \gamma \in N$,તો $\alpha+\beta+\gamma$ ની કિંમત શોધો.

$\begin{aligned} & A(\alpha, \beta)=\left[\begin{array}{ccc}\cos \alpha & \sin \alpha & 0 \\ -\sin \alpha & \cos \alpha & 0 \\ 0 & 0 & e^\beta\end{array}\right] \\ & \Rightarrow[A(\alpha, \beta)]^{-1}=\end{aligned}$

જો $A = \begin{bmatrix} 1 & 5 & 2 \\ 4 & 1 & 3 \\ 2 & 6 & 3 \end{bmatrix}$ હોય, તો $|(\operatorname{Adj} A)^{-1}| = $
