Ngā Upane Otinga

Tangohia te 11 i te \frac{646}{125}, ka -\frac{729}{125}.

$$\sqrt[3]{-\frac{729}{125}}-\sqrt{0.1^{-2}}+\sqrt[3]{8^{2}}$$

Tātaitia te \sqrt[3]{-\frac{729}{125}} kia tae ki -\frac{9}{5}.

$$-\frac{9}{5}-\sqrt{0.1^{-2}}+\sqrt[3]{8^{2}}$$

Tātaihia te 0.1 mā te pū o -2, kia riro ko 100.

$$-\frac{9}{5}-\sqrt{100}+\sqrt[3]{8^{2}}$$

Tātaitia te pūtakerua o 100 kia tae ki 10.

$$-\frac{9}{5}-10+\sqrt[3]{8^{2}}$$

Tangohia te 10 i te -\frac{9}{5}, ka -\frac{59}{5}.

$$-\frac{59}{5}+\sqrt[3]{8^{2}}$$

Tātaihia te 8 mā te pū o 2, kia riro ko 64.

$$-\frac{59}{5}+\sqrt[3]{64}$$

Tātaitia te \sqrt[3]{64} kia tae ki 4.

$$-\frac{59}{5}+4$$

Tāpirihia te -\frac{59}{5} ki te 4, ka -\frac{39}{5}.

$$-\frac{39}{5}$$
