Kua tāruatia ki te papatopenga

det(\left(\begin{matrix}3&-1&4\\2&3&-1\\-5&2&3\end{matrix}\right))

Kimihia te tau whakatau o te poukapa mā te whakamahi i te tikanga hauroki.

\left(\begin{matrix}3&-1&4&3&-1\\2&3&-1&2&3\\-5&2&3&-5&2\end{matrix}\right)

Whakaroatia te poukapa taketake mā te tāruarua i ngā tīwae tuatahi e rua hei tīwae tuawhā me te tuarima.

3\times 3\times 3-\left(-\left(-5\right)\right)+4\times 2\times 2=38

Tīmata atu i te tāurunga mauī o runga, whakareatia whakararo i ngā hauroki, ka tāpiri i ngā hua ka puta.

-5\times 3\times 4+2\left(-1\right)\times 3+3\times 2\left(-1\right)=-72

Tīmata atu i te tāurunga mauī o raro, whakareatia whakarunga i ngā hauroki, ka tāpiri i ngā hua ka puta.

38-\left(-72\right)

Tangohia te tapeke o ngā hauroki whakarunga mai i te tapeke o ngā hua hauroki whakararo.

110

Tango -72 mai i 38.

det(\left(\begin{matrix}3&-1&4\\2&3&-1\\-5&2&3\end{matrix}\right))

Kimihia te tau whakatau o te poukapa mā te whakamahi i te tikanga whakaroha ā-tauriki (te tikanga whakaroha ā-tauwehe tahi rānei).

3det(\left(\begin{matrix}3&-1\\2&3\end{matrix}\right))-\left(-det(\left(\begin{matrix}2&-1\\-5&3\end{matrix}\right))\right)+4det(\left(\begin{matrix}2&3\\-5&2\end{matrix}\right))

Hei whakaroha mā ngā tauriki, me whakarea ia huānga o te haupae tuatahi ki tana tauriki, arā, ko te tau whakatau o te poukapa 2\times 2 i hangā mā te muku i te haupae me te tīwae i roto anō taua huānga, kātahi ka whakarea ki te tohu tūnga o taua huānga.

3\left(3\times 3-2\left(-1\right)\right)-\left(-\left(2\times 3-\left(-5\left(-1\right)\right)\right)\right)+4\left(2\times 2-\left(-5\times 3\right)\right)

Mō te poukapa 2\times 2 \left(\begin{matrix}a&b\\c&d\end{matrix}\right), ko te ad-bc te tau whakatau.

3\times 11-\left(-1\right)+4\times 19

Whakarūnātia.

110

Tāpirihia ngā kīanga tau hei kimi i te otinga whakamutunga.
