Tohaina
Kua tāruatia ki te papatopenga
\sqrt{\frac{1}{20}}
Whakarohaina te \frac{0.1}{2} mā te whakarea i te taurunga me te tauraro ki te 10.
\frac{\sqrt{1}}{\sqrt{20}}
Tuhia anō te pūtake rua o te whakawehenga \sqrt{\frac{1}{20}} hei whakawehenga o ngā pūtake rua \frac{\sqrt{1}}{\sqrt{20}}.
\frac{1}{\sqrt{20}}
Tātaitia te pūtakerua o 1 kia tae ki 1.
\frac{1}{2\sqrt{5}}
Tauwehea te 20=2^{2}\times 5. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 5} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{5}. Tuhia te pūtakerua o te 2^{2}.
\frac{\sqrt{5}}{2\left(\sqrt{5}\right)^{2}}
Whakangāwaritia te tauraro o \frac{1}{2\sqrt{5}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{5}.
\frac{\sqrt{5}}{2\times 5}
Ko te pūrua o \sqrt{5} ko 5.
\frac{\sqrt{5}}{10}
Whakareatia te 2 ki te 5, ka 10.
