4\sqrt{5}+\frac{30}{\sqrt{5}}
Tauwehea te 80=4^{2}\times 5. Tuhia anō te pūtake rua o te hua \sqrt{4^{2}\times 5} hei hua o ngā pūtake rua \sqrt{4^{2}}\sqrt{5}. Tuhia te pūtakerua o te 4^{2}.
4\sqrt{5}+\frac{30\sqrt{5}}{\left(\sqrt{5}\right)^{2}}
Whakangāwaritia te tauraro o \frac{30}{\sqrt{5}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{5}.
4\sqrt{5}+\frac{30\sqrt{5}}{5}
Ko te pūrua o \sqrt{5} ko 5.
4\sqrt{5}+6\sqrt{5}
Whakawehea te 30\sqrt{5} ki te 5, kia riro ko 6\sqrt{5}.
10\sqrt{5}
Pahekotia te 4\sqrt{5} me 6\sqrt{5}, ka 10\sqrt{5}.
