Ngā Upane Otinga

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{\sqrt{5}}{\sqrt{10}}$$

Whakangāwaritia te tauraro o \frac{\sqrt{5}}{\sqrt{10}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{10}.

$$\frac{\sqrt{5}\sqrt{10}}{\left(\sqrt{10}\right)^{2}}$$

Ko te pūrua o \sqrt{10} ko 10.

$$\frac{\sqrt{5}\sqrt{10}}{10}$$

Tauwehea te 10=5\times 2. Tuhia anō te pūtake rua o te hua \sqrt{5\times 2} hei hua o ngā pūtake rua \sqrt{5}\sqrt{2}.

$$\frac{\sqrt{5}\sqrt{5}\sqrt{2}}{10}$$

Whakareatia te \sqrt{5} ki te \sqrt{5}, ka 5.

$$\frac{5\sqrt{2}}{10}$$

Whakawehea te 5\sqrt{2} ki te 10, kia riro ko \frac{1}{2}\sqrt{2}.

$$\frac{1}{2}\sqrt{2}$$
