Whakaoti i te (2/7)*sqrt{2}*sqrt{18}

$$( \frac{ 2 }{ 7 } ) \times \sqrt{ 2 } \times \sqrt{ 18 }$$

Aromātai

$$\frac{12}{7}\approx 1.714285714$$

Ngā Upane Otinga

Tauwehea te 18=2\times 9. Tuhia anō te pūtake rua o te hua \sqrt{2\times 9} hei hua o ngā pūtake rua \sqrt{2}\sqrt{9}.

$$\frac{2}{7}\sqrt{2}\sqrt{2}\sqrt{9}$$

Whakareatia te \sqrt{2} ki te \sqrt{2}, ka 2.

$$\frac{2}{7}\times 2\sqrt{9}$$

Tuhia te \frac{2}{7}\times 2 hei hautanga kotahi.

$$\frac{2\times 2}{7}\sqrt{9}$$

Whakareatia te 2 ki te 2, ka 4.

$$\frac{4}{7}\sqrt{9}$$

Tātaitia te pūtakerua o 9 kia tae ki 3.

$$\frac{4}{7}\times 3$$

Tuhia te \frac{4}{7}\times 3 hei hautanga kotahi.

$$\frac{4\times 3}{7}$$

Whakareatia te 4 ki te 3, ka 12.

$$\frac{12}{7}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 3}{7} = 1\frac{5}{7} = 1.7142857142857142$$
