Kua tāruatia ki te papatopenga
\sqrt{4}=\sqrt{\frac{12}{3}}
Tuhia anō te whakawehe o ngā pūtake rua \frac{\sqrt{12}}{\sqrt{3}} hei pūtake rua o te whakawehenga \sqrt{\frac{12}{3}} ka mahi i te whakawehenga.
2=\sqrt{\frac{12}{3}}
Tātaitia te pūtakerua o 4 kia tae ki 2.
2=\sqrt{4}
Whakawehea te 12 ki te 3, kia riro ko 4.
2=2
Tātaitia te pūtakerua o 4 kia tae ki 2.
\text{true}
Whakatauritea te 2 me te 2.
