Whakaoti i te 25a*13a*4a

$$25 a \cdot 13 a \cdot 4 a$$

Aromātai

$$1300a^{3}$$

Ngā Upane Otinga

Whakareatia te a ki te a, ka a^{2}.

$$25a^{2}\times 13\times 4a$$

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te 1 kia riro ai te 3.

$$25a^{3}\times 13\times 4$$

Whakareatia te 25 ki te 13, ka 325.

$$325a^{3}\times 4$$

Whakareatia te 325 ki te 4, ka 1300.

$$1300a^{3}$$

Kimi Pārōnaki e ai ki a

$$3900a^{2}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Whakareatia te a ki te a, ka a^{2}.

$$\frac{\mathrm{d}}{\mathrm{d}a}(25a^{2}\times 13\times 4a)$$

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te 1 kia riro ai te 3.

$$\frac{\mathrm{d}}{\mathrm{d}a}(25a^{3}\times 13\times 4)$$

Whakareatia te 25 ki te 13, ka 325.

$$\frac{\mathrm{d}}{\mathrm{d}a}(325a^{3}\times 4)$$

Whakareatia te 325 ki te 4, ka 1300.

$$\frac{\mathrm{d}}{\mathrm{d}a}(1300a^{3})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$3\times 1300a^{3-1}$$

Whakareatia 3 ki te 1300.

$$3900a^{3-1}$$

Tango 1 mai i 3.

$$3900a^{2}$$
