Kua tāruatia ki te papatopenga

det(\left(\begin{matrix}3&-1&-1\\4&3&-2\\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&-1&3&-1\\4&3&-2&4&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(-2\times 5\right)-4\left(-2\right)=45

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

5\times 3\left(-1\right)-2\left(-2\right)\times 3+3\times 4\left(-1\right)=-15

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

45-\left(-15\right)

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

Tango -15 mai i 45.

det(\left(\begin{matrix}3&-1&-1\\4&3&-2\\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&-2\\-2&3\end{matrix}\right))-\left(-det(\left(\begin{matrix}4&-2\\5&3\end{matrix}\right))\right)-det(\left(\begin{matrix}4&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-\left(-2\left(-2\right)\right)\right)-\left(-\left(4\times 3-5\left(-2\right)\right)\right)-\left(4\left(-2\right)-5\times 3\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 5-\left(-22\right)-\left(-23\right)

Whakarūnātia.

Tāpirihia ngā kīanga tau hei kimi i te otinga whakamutunga.
