Aromātai

$$\frac{27}{y^{2}}$$

Ngā Upane Otinga

Tātaihia te 3 mā te pū o -3, kia riro ko \frac{1}{27}.

$$\frac{1}{\frac{1}{27}}y^{-2}$$

Whakawehe 1 ki te \frac{1}{27} mā te whakarea 1 ki te tau huripoki o \frac{1}{27}.

$$1\times 27y^{-2}$$

Whakareatia te 1 ki te 27, ka 27.

$$27y^{-2}$$

Kimi Pārōnaki e ai ki y

$$-\frac{54}{y^{3}}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Tātaihia te 3 mā te pū o -3, kia riro ko \frac{1}{27}.

$$\frac{\mathrm{d}}{\mathrm{d}y}(\frac{1}{\frac{1}{27}}y^{-2})$$

Whakawehe 1 ki te \frac{1}{27} mā te whakarea 1 ki te tau huripoki o \frac{1}{27}.

$$\frac{\mathrm{d}}{\mathrm{d}y}(1\times 27y^{-2})$$

Whakareatia te 1 ki te 27, ka 27.

$$\frac{\mathrm{d}}{\mathrm{d}y}(27y^{-2})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$-2\times 27y^{-2-1}$$

Whakareatia -2 ki te 27.

$$-54y^{-2-1}$$

Tango 1 mai i -2.
