det(\left(\begin{matrix}3&4&6\\5&8&3\\8&9&10\end{matrix}\right))

Diagonal usulidan foydalanib matritsaning aniqlovchisini topish.

\left(\begin{matrix}3&4&6&3&4\\5&8&3&5&8\\8&9&10&8&9\end{matrix}\right)

Birinchi ikki ustunni to'rtinchi va beshinchi ustun sifatida qaytarish uchun asl matritsani kengaytirish.

3\times 8\times 10+4\times 3\times 8+6\times 5\times 9=606

Pastki chap kiritmadan boshlab diagonal kamayish tarafga ko'paytirish ha koʻpaytmalarni qo'shish.

8\times 8\times 6+9\times 3\times 3+10\times 5\times 4=665

Pastki chap kiritmadan boshlab diagonal ko'payish tarafga koʻpaytirish va koʻpaytmalarni qoʻshish.

606-665

Kamayib boruvchi diagonal koʻpaytmalarning yig'indisidan ko'payib boruvchi diagonal koʻpaytmalar yig'indisini ayirish.

606 dan 665 ni ayirish.

det(\left(\begin{matrix}3&4&6\\5&8&3\\8&9&10\end{matrix}\right))

Kichik a'zolarni kengaytirish usulidan foydalanib matritsaning aniqlovchisini topish (ko'paytiruvchilarni kengaytirish deb ham nomlanadi).

3det(\left(\begin{matrix}8&3\\9&10\end{matrix}\right))-4det(\left(\begin{matrix}5&3\\8&10\end{matrix}\right))+6det(\left(\begin{matrix}5&8\\8&9\end{matrix}\right))

Kichik a’zolarga kengaytirish uchun birinchi satrning har bir elementini o‘zining kichik a’zosiga ko‘paytiring, qaysiki ana shu elementga ega bo‘lgan satr va ustunni yo‘q qilish orqali yaratilgan 2\times 2 matritsasining maxraji hisoblanadi, so‘ngra elementning joylashuv belgisiga ko‘paytiring.

3\left(8\times 10-9\times 3\right)-4\left(5\times 10-8\times 3\right)+6\left(5\times 9-8\times 8\right)

\left(\begin{matrix}a&b\\c&d\end{matrix}\right) 2\times 2 matritsasi uchun, determinant ad-bc.
