Kua tāruatia ki te papatopenga
\frac{\sqrt{81}}{\sqrt{8}}
Tuhia anō te pūtake rua o te whakawehenga \sqrt{\frac{81}{8}} hei whakawehenga o ngā pūtake rua \frac{\sqrt{81}}{\sqrt{8}}.
\frac{9}{\sqrt{8}}
Tātaitia te pūtakerua o 81 kia tae ki 9.
\frac{9}{2\sqrt{2}}
Tauwehea te 8=2^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 2} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{2}. Tuhia te pūtakerua o te 2^{2}.
\frac{9\sqrt{2}}{2\left(\sqrt{2}\right)^{2}}
Whakangāwaritia te tauraro o \frac{9}{2\sqrt{2}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{2}.
\frac{9\sqrt{2}}{2\times 2}
Ko te pūrua o \sqrt{2} ko 2.
\frac{9\sqrt{2}}{4}
Whakareatia te 2 ki te 2, ka 4.
