Ngā Upane Otinga

Tangohia te 19 i te 100, ka 81.

$$\frac{4\sqrt{81}}{5\sqrt[3]{0.027}}$$

Tātaitia te pūtakerua o 81 kia tae ki 9.

$$\frac{4\times 9}{5\sqrt[3]{0.027}}$$

Whakareatia te 4 ki te 9, ka 36.

$$\frac{36}{5\sqrt[3]{0.027}}$$

Tātaitia te \sqrt[3]{0.027} kia tae ki \frac{3}{10}.

$$\frac{36}{5\times \frac{3}{10}}$$

Whakareatia te 5 ki te \frac{3}{10}, ka \frac{3}{2}.

$$\frac{36}{\frac{3}{2}}$$

Whakawehe 36 ki te \frac{3}{2} mā te whakarea 36 ki te tau huripoki o \frac{3}{2}.

$$36\times \frac{2}{3}$$

Whakareatia te 36 ki te \frac{2}{3}, ka 24.

$$24$$

Tauwehe

$$3\times 2^{3}$$
