0यदि \( \Delta=\left|\begin{array}{lll}a_{11} & a_{12} & a_{13} \\ a_{21} & a_{22} & a_{23} \\ a_{31} & a_{32} & a_{33}\end{array}\right| \) और \( a_{i j} \) का सहखण्ड in wa wa now
\( A_{i j} \) हो तो \( \Delta \) का मान निम्नलिखित रूप में व्यक्त किया जाता है:
(A) \( a_{11} A_{31}+a_{12} A_{32}+a_{13} A_{33} \)
(B) \( a_{11} A_{11}+a_{12} A_{21}+a_{13} A_{31} \)
(C) \( a_{21} A_{11}+a_{22} A_{12}+a_{23} A_{13} \)
(D) \( a_{11} A_{11}+a_{21} A_{21}+a_{31} A_{31} \)
