\frac{\sqrt{35}\sqrt{3}}{\sqrt{8}}
Hei whakarea \sqrt{5} me \sqrt{7}, whakareatia ngā tau i raro i te pūtake rua.
\frac{\sqrt{105}}{\sqrt{8}}
Hei whakarea \sqrt{35} me \sqrt{3}, whakareatia ngā tau i raro i te pūtake rua.
\frac{\sqrt{105}}{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{\sqrt{105}\sqrt{2}}{2\left(\sqrt{2}\right)^{2}}
Whakangāwaritia te tauraro o \frac{\sqrt{105}}{2\sqrt{2}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{2}.
\frac{\sqrt{105}\sqrt{2}}{2\times 2}
Ko te pūrua o \sqrt{2} ko 2.
\frac{\sqrt{210}}{2\times 2}
Hei whakarea \sqrt{105} me \sqrt{2}, whakareatia ngā tau i raro i te pūtake rua.
\frac{\sqrt{210}}{4}
Whakareatia te 2 ki te 2, ka 4.
