Whakaoti i te z^2*(-1)^2*3^2

$$z ^ { 2 } \cdot ( - 1 ) ^ { 2 } \cdot 3 ^ { 2 }$$

Aromātai

$$9z^{2}$$

Ngā Upane Otinga

Tātaihia te -1 mā te pū o 2, kia riro ko 1.

$$z^{2}\times 1\times 3^{2}$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$z^{2}\times 1\times 9$$

Whakareatia te 1 ki te 9, ka 9.

$$z^{2}\times 9$$

Kimi Pārōnaki e ai ki z

$$18z$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Tātaihia te -1 mā te pū o 2, kia riro ko 1.

$$\frac{\mathrm{d}}{\mathrm{d}z}(z^{2}\times 1\times 3^{2})$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$\frac{\mathrm{d}}{\mathrm{d}z}(z^{2}\times 1\times 9)$$

Whakareatia te 1 ki te 9, ka 9.

$$\frac{\mathrm{d}}{\mathrm{d}z}(z^{2}\times 9)$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$2\times 9z^{2-1}$$

Whakareatia 2 ki te 9.

$$18z^{2-1}$$

Tango 1 mai i 2.

$$18z^{1}$$

Mō tētahi kupu t, t^{1}=t.

$$18z$$
