Whakaoti i te 2xy^3/4xy^-1

$$\frac { 2 x y ^ { 3 } } { 4 x y ^ { - 1 } }$$

Aromātai

$$\frac{y^{4}}{2}$$

Ngā Upane Otinga

Me whakakore tahi te 2x i te taurunga me te tauraro.

$$\frac{y^{3}}{2\times \frac{1}{y}}$$

Hei whakawehe i ngā pū o te pūtake kotahi, tangohia te taupū o te tauraro mai i te taupū o te taurunga.

$$\frac{y^{4}}{2}$$

Kimi Pārōnaki e ai ki y

$$2y^{3}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Me whakakore tahi te 2x i te taurunga me te tauraro.

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

Hei whakawehe i ngā pū o te pūtake kotahi, tangohia te taupū o te tauraro mai i te taupū o te taurunga.

$$\frac{\mathrm{d}}{\mathrm{d}y}(\frac{y^{4}}{2})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$4\times \frac{1}{2}y^{4-1}$$

Whakareatia 4 ki te \frac{1}{2}.

$$2y^{4-1}$$

Tango 1 mai i 4.

$$2y^{3}$$
