Ngā Upane Otinga

Tātaihia te 9 mā te pū o 2, kia riro ko 81.

$$\sqrt{81+9^{2}+2\times 9\times 9\times 0.5}$$

Tātaihia te 9 mā te pū o 2, kia riro ko 81.

$$\sqrt{81+81+2\times 9\times 9\times 0.5}$$

Tāpirihia te 81 ki te 81, ka 162.

$$\sqrt{162+2\times 9\times 9\times 0.5}$$

Whakareatia te 2 ki te 9, ka 18.

$$\sqrt{162+18\times 9\times 0.5}$$

Whakareatia te 18 ki te 9, ka 162.

$$\sqrt{162+162\times 0.5}$$

Whakareatia te 162 ki te 0.5, ka 81.

$$\sqrt{162+81}$$

Tāpirihia te 162 ki te 81, ka 243.

$$\sqrt{243}$$

Tauwehea te 243=9^{2}\times 3. Tuhia anō te pūtake rua o te hua \sqrt{9^{2}\times 3} hei hua o ngā pūtake rua \sqrt{9^{2}}\sqrt{3}. Tuhia te pūtakerua o te 9^{2}.
