Ngā Upane Otinga

Kia whakarewa i te \frac{-r^{4}}{64r^{7}} ki tētahi taupū, me whakarewa tahi te taurunga me te tauraro ki te taupū kātahi ka whakawehe.

$$\frac{\left(-r^{4}\right)^{\frac{2}{3}}}{\left(64r^{7}\right)^{\frac{2}{3}}}$$

Whakarohaina te \left(64r^{7}\right)^{\frac{2}{3}}.

$$\frac{\left(-r^{4}\right)^{\frac{2}{3}}}{64^{\frac{2}{3}}\left(r^{7}\right)^{\frac{2}{3}}}$$

Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te 7 me te \frac{2}{3} kia riro ai te \frac{14}{3}.

$$\frac{\left(-r^{4}\right)^{\frac{2}{3}}}{64^{\frac{2}{3}}r^{\frac{14}{3}}}$$

Tātaihia te 64 mā te pū o \frac{2}{3}, kia riro ko 16.

$$\frac{\left(-r^{4}\right)^{\frac{2}{3}}}{16r^{\frac{14}{3}}}$$

Whakarohaina te \left(-r^{4}\right)^{\frac{2}{3}}.

$$\frac{\left(-1\right)^{\frac{2}{3}}\left(r^{4}\right)^{\frac{2}{3}}}{16r^{\frac{14}{3}}}$$

Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te 4 me te \frac{2}{3} kia riro ai te \frac{8}{3}.

$$\frac{\left(-1\right)^{\frac{2}{3}}r^{\frac{8}{3}}}{16r^{\frac{14}{3}}}$$

Tātaihia te -1 mā te pū o \frac{2}{3}, kia riro ko 1.

$$\frac{1r^{\frac{8}{3}}}{16r^{\frac{14}{3}}}$$

Me whakakore tahi te r^{\frac{8}{3}} i te taurunga me te tauraro.

Ngā Upane e Whakamahi ana i te Ture Mekameka

Mēnā ko F te hanganga o ngā pānga e rua e taea ana te pārōnaki f\left(u\right) me u=g\left(x\right), arā, mēnā ko F\left(x\right)=f\left(g\left(x\right)\right), ko te pārōnaki o F te pārōnaki o f e ai ki u whakareatia te pārōnaki o g e ai ki x, arā, \frac{\mathrm{d}}{\mathrm{d}x}(F)\left(x\right)=\frac{\mathrm{d}}{\mathrm{d}x}(f)\left(g\left(x\right)\right)\frac{\mathrm{d}}{\mathrm{d}x}(g)\left(x\right).

$$\frac{2}{3}\times \left(\frac{-r^{4}}{64r^{7}}\right)^{\frac{2}{3}-1}\frac{\mathrm{d}}{\mathrm{d}r}(\frac{-r^{4}}{64r^{7}})$$

Mō ngā pānga e rua e taea ana te pārōnaki, ko te pārōnaki o te otinga o ngā pānga e rua ko te tauraro whakareatia ki te pārōnaki o te taurunga tango i te taurunga whakareatia ki te pārōnaki o te tauraro, ā, ka whakawehea te katoa ki te tauraro kua pūruatia.

$$\frac{\frac{2}{3}\times \left(\frac{-r^{4}}{64r^{7}}\right)^{\frac{2}{3}-1}\left(64r^{7}\frac{\mathrm{d}}{\mathrm{d}r}(-r^{4})-\left(-r^{4}\frac{\mathrm{d}}{\mathrm{d}r}(64r^{7})\right)\right)}{\left(64r^{7}\right)^{2}}$$

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}.

$$\frac{\frac{2}{3}\times \left(\frac{-r^{4}}{64r^{7}}\right)^{\frac{2}{3}-1}\left(64r^{7}\times 4\left(-1\right)r^{4-1}-\left(-r^{4}\times 7\times 64r^{7-1}\right)\right)}{\left(64r^{7}\right)^{2}}$$

Whakareatia 64r^{7} ki te 4\left(-1\right)r^{4-1}.

$$\frac{\frac{2}{3}\times \left(\frac{-r^{4}}{64r^{7}}\right)^{-\frac{1}{3}}\left(-256r^{7}r^{3}-\left(-r^{4}\times 7\times 64r^{7-1}\right)\right)}{\left(64r^{7}\right)^{2}}$$

Whakareatia -r^{4} ki te 7\times 64r^{7-1}.

$$\frac{\frac{2}{3}\times \left(\frac{-r^{4}}{64r^{7}}\right)^{-\frac{1}{3}}\left(-256r^{10}-\left(-448r^{4}r^{6}\right)\right)}{\left(64r^{7}\right)^{2}}$$

Whakarūnātia.

$$\frac{\frac{2}{3}\times \left(\frac{-r^{4}}{64r^{7}}\right)^{-\frac{1}{3}}\left(-256r^{10}-\left(-448r^{10}\right)\right)}{\left(64r^{7}\right)^{2}}$$
