Tohaina
Kua tāruatia ki te papatopenga
\frac{3\sqrt{2}}{8\sqrt{2}-5\sqrt{2}}
Tauwehea te 128=8^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{8^{2}\times 2} hei hua o ngā pūtake rua \sqrt{8^{2}}\sqrt{2}. Tuhia te pūtakerua o te 8^{2}.
\frac{3\sqrt{2}}{3\sqrt{2}}
Pahekotia te 8\sqrt{2} me -5\sqrt{2}, ka 3\sqrt{2}.
