Whakaoti i te (frac{3sqrt{2}}{5})^2

$$( \frac { 3 \sqrt { 2 } } { 5 } ) ^ { 2 }$$

Aromātai

$$\frac{18}{25}=0.72$$

Ngā Upane Otinga

Kia whakarewa i te \frac{3\sqrt{2}}{5} ki tētahi taupū, me whakarewa tahi te taurunga me te tauraro ki te taupū kātahi ka whakawehe.

$$\frac{\left(3\sqrt{2}\right)^{2}}{5^{2}}$$

Whakarohaina te \left(3\sqrt{2}\right)^{2}.

$$\frac{3^{2}\left(\sqrt{2}\right)^{2}}{5^{2}}$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$\frac{9\left(\sqrt{2}\right)^{2}}{5^{2}}$$

Ko te pūrua o \sqrt{2} ko 2.

$$\frac{9\times 2}{5^{2}}$$

Whakareatia te 9 ki te 2, ka 18.

$$\frac{18}{5^{2}}$$

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$\frac{18}{25}$$

Tauwehe

$$\frac{2 \cdot 3 ^ {2}}{5 ^ {2}} = 0.72$$
