Whakaoti i te (-y^3)*(-y^4)=?

$$( - y ^ { 3 } ) \cdot ( - y ^ { 4 } ) = ?$$

Aromātai

$$y^{7}$$

Ngā Upane Otinga

Whakareatia te -1 ki te -1, ka 1.

$$y^{3}y^{4}$$

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 3 me te 4 kia riro ai te 7.

$$y^{7}$$

Kimi Pārōnaki e ai ki y

$$7y^{6}$$

Ngā Upane e Whakamahi ana i te Ture Pārōnaki mō te Hua

Mo ētahi pānga e rua e taea ana te pārōnaki, ko te pārōnaki o te hua o ngā pānga e rua ko te pānga tuatahi whakareatia ki te pārōnaki o te pānga tuarua tāpiri i te pānga tuarua whakareatia ki te pārōnaki o te mea tuatahi.

$$-y^{3}\frac{\mathrm{d}}{\mathrm{d}y}(-y^{4})-y^{4}\frac{\mathrm{d}}{\mathrm{d}y}(-y^{3})$$

Ko te pārōnaki o tētahi pūrau ko te tapeke o ngā pārōnaki o ōna kīanga tau. Ko te pārōnaki o tētahi kīanga tau pūmau ko 0. Ko te pārōnaki o te ax^{n} ko te nax^{n-1}.

$$-y^{3}\times 4\left(-1\right)y^{4-1}-y^{4}\times 3\left(-1\right)y^{3-1}$$

Whakarūnātia.

$$-y^{3}\left(-4\right)y^{3}-y^{4}\left(-3\right)y^{2}$$

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

$$-4\left(-1\right)y^{3+3}-\left(-3y^{4+2}\right)$$

Whakarūnātia.

$$4y^{6}+3y^{6}$$

Pahekotia ngā kīanga tau ōrite.

$$\left(4+3\right)y^{6}$$

Tāpiri 4 ki te 3.

$$7y^{6}$$
