\frac{\left(\sqrt{2}-1\right)\sqrt{5}}{\left(\sqrt{5}\right)^{2}}
Whakangāwaritia te tauraro o \frac{\sqrt{2}-1}{\sqrt{5}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{5}.
\frac{\left(\sqrt{2}-1\right)\sqrt{5}}{5}
Ko te pūrua o \sqrt{5} ko 5.
\frac{\sqrt{2}\sqrt{5}-\sqrt{5}}{5}
Whakamahia te āhuatanga tohatoha hei whakarea te \sqrt{2}-1 ki te \sqrt{5}.
\frac{\sqrt{10}-\sqrt{5}}{5}
Hei whakarea \sqrt{2} me \sqrt{5}, whakareatia ngā tau i raro i te pūtake rua.
