Ngā Upane Otinga

Tauwehea te 600=10^{2}\times 6. Tuhia anō te pūtake rua o te hua \sqrt{10^{2}\times 6} hei hua o ngā pūtake rua \sqrt{10^{2}}\sqrt{6}. Tuhia te pūtakerua o te 10^{2}.

$$\frac{1}{2}\times 10\sqrt{6}\times 18^{2}$$

Whakareatia te \frac{1}{2} ki te 10, ka \frac{10}{2}.

$$\frac{10}{2}\sqrt{6}\times 18^{2}$$

Whakawehea te 10 ki te 2, kia riro ko 5.

$$5\sqrt{6}\times 18^{2}$$

Tātaihia te 18 mā te pū o 2, kia riro ko 324.

$$5\sqrt{6}\times 324$$

Whakareatia te 5 ki te 324, ka 1620.

$$1620\sqrt{6}$$
