Ngā Upane Otinga

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

$$\frac{6561+3^{6}}{3^{9}-3^{7}}$$

Tātaihia te 3 mā te pū o 6, kia riro ko 729.

$$\frac{6561+729}{3^{9}-3^{7}}$$

Tāpirihia te 6561 ki te 729, ka 7290.

$$\frac{7290}{3^{9}-3^{7}}$$

Tātaihia te 3 mā te pū o 9, kia riro ko 19683.

$$\frac{7290}{19683-3^{7}}$$

Tātaihia te 3 mā te pū o 7, kia riro ko 2187.

$$\frac{7290}{19683-2187}$$

Tangohia te 2187 i te 19683, ka 17496.

$$\frac{7290}{17496}$$

Whakahekea te hautanga \frac{7290}{17496} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 1458.

$$\frac{5}{12}$$

Tauwehe

$$\frac{5}{2 ^ {2} \cdot 3} = 0.4166666666666667$$
