Ngā Upane Otinga

Tangohia te \frac{1}{4} i te 2, ka \frac{7}{4}.

$$\left(\frac{7}{4}\left(3-\frac{1}{2}\right)\right)^{2}-\sqrt{\frac{4}{9}}$$

Tangohia te \frac{1}{2} i te 3, ka \frac{5}{2}.

$$\left(\frac{7}{4}\times \frac{5}{2}\right)^{2}-\sqrt{\frac{4}{9}}$$

Whakareatia te \frac{7}{4} ki te \frac{5}{2}, ka \frac{35}{8}.

$$\left(\frac{35}{8}\right)^{2}-\sqrt{\frac{4}{9}}$$

Tātaihia te \frac{35}{8} mā te pū o 2, kia riro ko \frac{1225}{64}.

$$\frac{1225}{64}-\sqrt{\frac{4}{9}}$$

Tuhia anō te pūtake rua o te whakawehenga \frac{4}{9} hei whakawehenga o ngā pūtake rua \frac{\sqrt{4}}{\sqrt{9}}. Tuhia te pūtakerua o te taurunga me te tauraro.

$$\frac{1225}{64}-\frac{2}{3}$$

Tangohia te \frac{2}{3} i te \frac{1225}{64}, ka \frac{3547}{192}.

$$\frac{3547}{192}$$

Tauwehe

$$\frac{3547}{2 ^ {6} \cdot 3} = 18\frac{91}{192} = 18.473958333333332$$
