Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 4 me te 4 kia riro ai te 8.

$$\frac{\frac{3^{8}}{21^{2}}}{21^{2}}$$

Tātaihia te 3 mā te pū o 8, kia riro ko 6561.

$$\frac{\frac{6561}{21^{2}}}{21^{2}}$$

Tātaihia te 21 mā te pū o 2, kia riro ko 441.

$$\frac{\frac{6561}{441}}{21^{2}}$$

Whakahekea te hautanga \frac{6561}{441} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.

$$\frac{\frac{729}{49}}{21^{2}}$$

Tātaihia te 21 mā te pū o 2, kia riro ko 441.

$$\frac{\frac{729}{49}}{441}$$

Tuhia te \frac{\frac{729}{49}}{441} hei hautanga kotahi.

$$\frac{729}{49\times 441}$$

Whakareatia te 49 ki te 441, ka 21609.

$$\frac{729}{21609}$$

Whakahekea te hautanga \frac{729}{21609} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.

$$\frac{81}{2401}$$
