Kua tāruatia ki te papatopenga
174\sqrt{5}-2\sqrt{2}-2\sqrt{5}-\sqrt{18}
Tauwehea te 20=2^{2}\times 5. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 5} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{5}. Tuhia te pūtakerua o te 2^{2}.
172\sqrt{5}-2\sqrt{2}-\sqrt{18}
Pahekotia te 174\sqrt{5} me -2\sqrt{5}, ka 172\sqrt{5}.
172\sqrt{5}-2\sqrt{2}-3\sqrt{2}
Tauwehea te 18=3^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{3^{2}\times 2} hei hua o ngā pūtake rua \sqrt{3^{2}}\sqrt{2}. Tuhia te pūtakerua o te 3^{2}.
172\sqrt{5}-5\sqrt{2}
Pahekotia te -2\sqrt{2} me -3\sqrt{2}, ka -5\sqrt{2}.
