\frac{80}{2\sqrt{10}\sqrt{170}}
Tauwehea te 40=2^{2}\times 10. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 10} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{10}. Tuhia te pūtakerua o te 2^{2}.
\frac{80}{2\sqrt{10}\sqrt{10}\sqrt{17}}
Tauwehea te 170=10\times 17. Tuhia anō te pūtake rua o te hua \sqrt{10\times 17} hei hua o ngā pūtake rua \sqrt{10}\sqrt{17}.
\frac{80}{2\times 10\sqrt{17}}
Whakareatia te \sqrt{10} ki te \sqrt{10}, ka 10.
\frac{80\sqrt{17}}{2\times 10\left(\sqrt{17}\right)^{2}}
Whakangāwaritia te tauraro o \frac{80}{2\times 10\sqrt{17}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{17}.
\frac{80\sqrt{17}}{2\times 10\times 17}
Ko te pūrua o \sqrt{17} ko 17.
\frac{4\sqrt{17}}{17}
Me whakakore tahi te 2\times 10 i te taurunga me te tauraro.
