$$\frac{4\times \left(\frac{b}{c}\right)^{2}a^{4}}{9}$$

Ngā Upane Otinga

Kia whakarewa i te \frac{-2a^{2}b}{3c} ki tētahi taupū, me whakarewa tahi te taurunga me te tauraro ki te taupū kātahi ka whakawehe.

$$\frac{\left(-2a^{2}b\right)^{2}}{\left(3c\right)^{2}}$$

Whakarohaina te \left(-2a^{2}b\right)^{2}.

$$\frac{\left(-2\right)^{2}\left(a^{2}\right)^{2}b^{2}}{\left(3c\right)^{2}}$$

Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te 2 me te 2 kia riro ai te 4.

$$\frac{\left(-2\right)^{2}a^{4}b^{2}}{\left(3c\right)^{2}}$$

Tātaihia te -2 mā te pū o 2, kia riro ko 4.

$$\frac{4a^{4}b^{2}}{\left(3c\right)^{2}}$$

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

$$\frac{4a^{4}b^{2}}{3^{2}c^{2}}$$

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

$$\frac{4a^{4}b^{2}}{9c^{2}}$$
