Whakaoti i te (91*y)(-105*10y)

$$( 91 \times y ) ( - 105 \times 10 y )$$

Aromātai

$$-95550y^{2}$$

Ngā Upane Otinga

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

$$91y^{2}\left(-105\right)\times 10$$

Whakareatia te 91 ki te -105, ka -9555.

$$-9555y^{2}\times 10$$

Whakareatia te -9555 ki te 10, ka -95550.

$$-95550y^{2}$$

Kimi Pārōnaki e ai ki y

$$-191100y$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

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

$$\frac{\mathrm{d}}{\mathrm{d}y}(91y^{2}\left(-105\right)\times 10)$$

Whakareatia te 91 ki te -105, ka -9555.

$$\frac{\mathrm{d}}{\mathrm{d}y}(-9555y^{2}\times 10)$$

Whakareatia te -9555 ki te 10, ka -95550.

$$\frac{\mathrm{d}}{\mathrm{d}y}(-95550y^{2})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$2\left(-95550\right)y^{2-1}$$

Whakareatia 2 ki te -95550.

$$-191100y^{2-1}$$

Tango 1 mai i 2.

$$-191100y^{1}$$

Mō tētahi kupu t, t^{1}=t.

$$-191100y$$
