Whakaoti i te 2x^6*3x^-9

$$2 x ^ { 6 } \times 3 x ^ { - 9 }$$

Aromātai

$$\frac{6}{x^{3}}$$

Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 6 me te -9 kia riro ai te -3.

$$2x^{-3}\times 3$$

Whakareatia te 2 ki te 3, ka 6.

$$6x^{-3}$$

Kimi Pārōnaki e ai ki x

$$-\frac{18}{x^{4}}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 6 me te -9 kia riro ai te -3.

$$\frac{\mathrm{d}}{\mathrm{d}x}(2x^{-3}\times 3)$$

Whakareatia te 2 ki te 3, ka 6.

$$\frac{\mathrm{d}}{\mathrm{d}x}(6x^{-3})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$-3\times 6x^{-3-1}$$

Whakareatia -3 ki te 6.

$$-18x^{-3-1}$$

Tango 1 mai i -3.

$$-18x^{-4}$$
