Ngā Upane Otinga

Tātaihia te 20 mā te pū o 3, kia riro ko 8000.

$$\frac{8000\times 25^{2}\times 4}{2^{7}}$$

Tātaihia te 25 mā te pū o 2, kia riro ko 625.

$$\frac{8000\times 625\times 4}{2^{7}}$$

Whakareatia te 8000 ki te 625, ka 5000000.

$$\frac{5000000\times 4}{2^{7}}$$

Whakareatia te 5000000 ki te 4, ka 20000000.

$$\frac{20000000}{2^{7}}$$

Tātaihia te 2 mā te pū o 7, kia riro ko 128.

$$\frac{20000000}{128}$$

Whakawehea te 20000000 ki te 128, kia riro ko 156250.

$$156250$$
