Ngā Upane mō te Hua o ngā Pānga Taupū e Rua

Whakamahia ngā ture taupū hei whakarūnā i te kīanga.

$$\left(12x^{2}\right)^{1}\times \frac{1}{-4x^{2}}$$

Hei hiki i te hua o ngā tau e rua, neke atu rānei ki tētahi pū, hīkina ia tau ki te pū ka tuhi ko tāna hua.

$$12^{1}\left(x^{2}\right)^{1}\times \frac{1}{-4}\times \frac{1}{x^{2}}$$

Whakamahia te Āhuatanga Kōaro o te Whakareanga.

$$12^{1}\times \frac{1}{-4}\left(x^{2}\right)^{1}\times \frac{1}{x^{2}}$$

Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū.

$$12^{1}\times \frac{1}{-4}x^{2}x^{2\left(-1\right)}$$

Whakareatia 2 ki te -1.

$$12^{1}\times \frac{1}{-4}x^{2}x^{-2}$$

Hei whakarea pū o te pūtake ōrite, tāpiri ana taupū.

$$12^{1}\times \frac{1}{-4}x^{2-2}$$

Tāpirihia ngā taupū 2 me -2.

$$12^{1}\times \frac{1}{-4}x^{0}$$

Hīkina te 12 ki te pū 1.

$$12\times \frac{1}{-4}x^{0}$$

Hīkina te -4 ki te pū -1.

$$12\left(-\frac{1}{4}\right)x^{0}$$

Whakareatia 12 ki te -\frac{1}{4}.

Ngā Upane mō te Otinga o ngā Pānga Taupū

Whakamahia ngā ture taupū hei whakarūnā i te kīanga.

$$\frac{12^{1}x^{2}}{\left(-4\right)^{1}x^{2}}$$

Hei whakawehe i ngā pū o te pūtake kotahi, tangohia te taupū o te tauraro mai i te taupū o te taurunga.

$$\frac{12^{1}x^{2-2}}{\left(-4\right)^{1}}$$

Tango 2 mai i 2.

$$\frac{12^{1}x^{0}}{\left(-4\right)^{1}}$$

Mō tētahi tau a mahue te 0, a^{0}=1.

$$\frac{12^{1}}{\left(-4\right)^{1}}$$

Whakawehe 12 ki te -4.
