Whakaoti i te c_4^4*0.8^4*0.2^0=

$$c _ { 4 } ^ { 4 } \cdot 0.8 ^ { 4 } \cdot 0.2 ^ { 0 } =$$

Aromātai

$$\frac{256c_{4}^{4}}{625}$$

Ngā Upane Otinga

Tātaihia te 0.8 mā te pū o 4, kia riro ko 0.4096.

$$c_{4}^{4}\times 0.4096\times 0.2^{0}$$

Tātaihia te 0.2 mā te pū o 0, kia riro ko 1.

$$c_{4}^{4}\times 0.4096\times 1$$

Whakareatia te 0.4096 ki te 1, ka 0.4096.

$$c_{4}^{4}\times 0.4096$$

Kimi Pārōnaki e ai ki c_4

$$\frac{1024c_{4}^{3}}{625}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Tātaihia te 0.8 mā te pū o 4, kia riro ko 0.4096.

$$\frac{\mathrm{d}}{\mathrm{d}c_{4}}(c_{4}^{4}\times 0.4096\times 0.2^{0})$$

Tātaihia te 0.2 mā te pū o 0, kia riro ko 1.

$$\frac{\mathrm{d}}{\mathrm{d}c_{4}}(c_{4}^{4}\times 0.4096\times 1)$$

Whakareatia te 0.4096 ki te 1, ka 0.4096.

$$\frac{\mathrm{d}}{\mathrm{d}c_{4}}(c_{4}^{4}\times 0.4096)$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$4\times 0.4096c_{4}^{4-1}$$

Whakareatia 4 ki te 0.4096.

$$1.6384c_{4}^{4-1}$$

Tango 1 mai i 4.

$$1.6384c_{4}^{3}$$
