Ngā Upane Otinga

Tauwehea te 24=2^{2}\times 6. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 6} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{6}. Tuhia te pūtakerua o te 2^{2}.

$$\left(2\sqrt{6}-\sqrt{54}\right)\times \frac{1}{56}$$

Tauwehea te 54=3^{2}\times 6. Tuhia anō te pūtake rua o te hua \sqrt{3^{2}\times 6} hei hua o ngā pūtake rua \sqrt{3^{2}}\sqrt{6}. Tuhia te pūtakerua o te 3^{2}.

$$\left(2\sqrt{6}-3\sqrt{6}\right)\times \frac{1}{56}$$

Pahekotia te 2\sqrt{6} me -3\sqrt{6}, ka -\sqrt{6}.

$$-\sqrt{6}\times \frac{1}{56}$$

Whakareatia te -1 ki te \frac{1}{56}, ka -\frac{1}{56}.

$$-\frac{1}{56}\sqrt{6}$$
