Kua tāruatia ki te papatopenga
\frac{\sqrt{8}}{\sqrt{15}}
Tuhia anō te pūtake rua o te whakawehenga \sqrt{\frac{8}{15}} hei whakawehenga o ngā pūtake rua \frac{\sqrt{8}}{\sqrt{15}}.
\frac{2\sqrt{2}}{\sqrt{15}}
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{2\sqrt{2}\sqrt{15}}{\left(\sqrt{15}\right)^{2}}
Whakangāwaritia te tauraro o \frac{2\sqrt{2}}{\sqrt{15}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{15}.
\frac{2\sqrt{2}\sqrt{15}}{15}
Ko te pūrua o \sqrt{15} ko 15.
\frac{2\sqrt{30}}{15}
Hei whakarea \sqrt{2} me \sqrt{15}, whakareatia ngā tau i raro i te pūtake rua.
