Kua tāruatia ki te papatopenga
\frac{5+\sqrt{7}}{\left(5-\sqrt{7}\right)\left(5+\sqrt{7}\right)}
Whakangāwaritia te tauraro o \frac{1}{5-\sqrt{7}} mā te whakarea i te taurunga me te tauraro ki te 5+\sqrt{7}.
\frac{5+\sqrt{7}}{5^{2}-\left(\sqrt{7}\right)^{2}}
Whakaarohia te \left(5-\sqrt{7}\right)\left(5+\sqrt{7}\right). Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
\frac{5+\sqrt{7}}{25-7}
Pūrua 5. Pūrua \sqrt{7}.
\frac{5+\sqrt{7}}{18}
Tangohia te 7 i te 25, ka 18.
