Whakaoti i te 0.3a(-2a)*3.overline{3}

$$0.3 a ( - 2 a ) \cdot 3 . \overline { 3 }$$

Aromātai

$$-\frac{9a^{2}}{5}$$

Ngā Upane Otinga

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

$$0.3a^{2}\left(-2\right)\times 3$$

Whakareatia te 0.3 ki te -2, ka -0.6.

$$-0.6a^{2}\times 3$$

Whakareatia te -0.6 ki te 3, ka -1.8.

$$-1.8a^{2}$$

Kimi Pārōnaki e ai ki a

$$-\frac{18a}{5}$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

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

$$\frac{\mathrm{d}}{\mathrm{d}a}(0.3a^{2}\left(-2\right)\times 3)$$

Whakareatia te 0.3 ki te -2, ka -0.6.

$$\frac{\mathrm{d}}{\mathrm{d}a}(-0.6a^{2}\times 3)$$

Whakareatia te -0.6 ki te 3, ka -1.8.

$$\frac{\mathrm{d}}{\mathrm{d}a}(-1.8a^{2})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$2\left(-1.8\right)a^{2-1}$$

Whakareatia 2 ki te -1.8.

$$-3.6a^{2-1}$$

Tango 1 mai i 2.

$$-3.6a^{1}$$

Mō tētahi kupu t, t^{1}=t.

$$-3.6a$$
