5 raruraru e ōrite ana ki:
\frac { \sqrt { 50 } - \sqrt { 18 } } { \sqrt { 200 } }
Tohaina
Kua tāruatia ki te papatopenga
\frac{5\sqrt{2}-\sqrt{18}}{\sqrt{200}}
Tauwehea te 50=5^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{5^{2}\times 2} hei hua o ngā pūtake rua \sqrt{5^{2}}\sqrt{2}. Tuhia te pūtakerua o te 5^{2}.
\frac{5\sqrt{2}-3\sqrt{2}}{\sqrt{200}}
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}.
\frac{2\sqrt{2}}{\sqrt{200}}
Pahekotia te 5\sqrt{2} me -3\sqrt{2}, ka 2\sqrt{2}.
\frac{2\sqrt{2}}{10\sqrt{2}}
Tauwehea te 200=10^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{10^{2}\times 2} hei hua o ngā pūtake rua \sqrt{10^{2}}\sqrt{2}. Tuhia te pūtakerua o te 10^{2}.
\frac{1}{5}
