Ngā Upane Otinga

Tauwehea te 39=13\times 3. Tuhia anō te pūtake rua o te hua \sqrt{13\times 3} hei hua o ngā pūtake rua \sqrt{13}\sqrt{3}.

$$4\times 5\sqrt{13}\sqrt{3}\sqrt{13}\sqrt{3}$$

Whakareatia te \sqrt{13} ki te \sqrt{13}, ka 13.

$$4\times 5\times 13\sqrt{3}\sqrt{3}$$

Whakareatia te \sqrt{3} ki te \sqrt{3}, ka 3.

$$4\times 5\times 13\times 3$$

Whakareatia te 4 ki te 5, ka 20.

$$20\times 13\times 3$$

Whakareatia te 20 ki te 13, ka 260.

$$260\times 3$$

Whakareatia te 260 ki te 3, ka 780.

$$780$$

Tauwehe

$$2^{2}\times 3\times 5\times 13$$
