Whakaoti i te -8a^3b^5/4a^4b^4

$$\frac { - 8 a ^ { 3 } b ^ { 5 } } { 4 a ^ { 4 } b ^ { 4 } }$$

Aromātai

$$-\frac{2b}{a}$$

Ngā Upane e Whakamahi ana i te Āhuatanga o te Otinga o ngā Pū

Whakamahia ngā ture taupū hei whakarūnā i te kīanga.

$$\frac{\left(-8\right)^{1}a^{3}b^{5}}{4^{1}a^{4}b^{4}}$$

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

$$\frac{\left(-8\right)^{1}}{4^{1}}a^{3-4}b^{5-4}$$

Tango 4 mai i 3.

$$\frac{\left(-8\right)^{1}}{4^{1}}\times \frac{1}{a}b^{5-4}$$

Tango 4 mai i 5.

$$\frac{\left(-8\right)^{1}}{4^{1}}\times \frac{1}{a}b^{1}$$

Whakawehe -8 ki te 4.

$$-2\times \frac{1}{a}b$$

Kimi Pārōnaki e ai ki a

$$\frac{2b}{a^{2}}$$

Ngā Upane Otinga

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

$$\frac{\mathrm{d}}{\mathrm{d}a}(\left(-\frac{8b^{5}}{4b^{4}}\right)a^{3-4})$$

Mahia ngā tātaitanga.

$$\frac{\mathrm{d}}{\mathrm{d}a}(\left(-2b\right)\times \frac{1}{a})$$

Ko te pārōnaki o tētahi pūrau ko te tapeke o ngā pārōnaki o ōna kīanga tau. Ko te pārōnaki o tētahi kīanga tau pūmau ko 0. Ko te pārōnaki o te ax^{n} ko te nax^{n-1}.

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

Mahia ngā tātaitanga.

$$2ba^{-2}$$
