Kua tāruatia ki te papatopenga
\sqrt{\frac{16+9}{16}\times 0.0256}
Whakareatia te 1 ki te 16, ka 16.
\sqrt{\frac{25}{16}\times 0.0256}
Tāpirihia te 16 ki te 9, ka 25.
\sqrt{\frac{25}{16}\times \frac{16}{625}}
Me tahuri ki tau ā-ira 0.0256 ki te hautau \frac{256}{10000}. Whakahekea te hautanga \frac{256}{10000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 16.
\sqrt{\frac{25\times 16}{16\times 625}}
Me whakarea te \frac{25}{16} ki te \frac{16}{625} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\sqrt{\frac{25}{625}}
Me whakakore tahi te 16 i te taurunga me te tauraro.
\sqrt{\frac{1}{25}}
Whakahekea te hautanga \frac{25}{625} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.
\frac{1}{5}
Tuhia anō te pūtake rua o te whakawehenga \frac{1}{25} hei whakawehenga o ngā pūtake rua \frac{\sqrt{1}}{\sqrt{25}}. Tuhia te pūtakerua o te taurunga me te tauraro.
