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

Whakamahia ngā ture taupū hei whakarūnā i te kīanga.

$$\frac{\left(-\frac{12}{7}\right)^{1}a^{4}b^{4}}{\left(-\frac{6}{7}\right)^{1}a^{3}b^{2}}$$

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

$$\frac{\left(-\frac{12}{7}\right)^{1}}{\left(-\frac{6}{7}\right)^{1}}a^{4-3}b^{4-2}$$

Tango 3 mai i 4.

$$\frac{\left(-\frac{12}{7}\right)^{1}}{\left(-\frac{6}{7}\right)^{1}}a^{1}b^{4-2}$$

Tango 2 mai i 4.

$$\frac{\left(-\frac{12}{7}\right)^{1}}{\left(-\frac{6}{7}\right)^{1}}ab^{2}$$

Whakawehe -\frac{12}{7} ki te -\frac{6}{7} mā te whakarea -\frac{12}{7} ki te tau huripoki o -\frac{6}{7}.
