Ngā Upane Otinga

Whakareatia te 9 ki te 2, ka 18.

$$\frac{18\times 2.5}{25\times 10^{-4}}$$

Whakareatia te 18 ki te 2.5, ka 45.

$$\frac{45}{25\times 10^{-4}}$$

Tātaihia te 10 mā te pū o -4, kia riro ko \frac{1}{10000}.

$$\frac{45}{25\times \frac{1}{10000}}$$

Whakareatia te 25 ki te \frac{1}{10000}, ka \frac{1}{400}.

$$\frac{45}{\frac{1}{400}}$$

Whakawehe 45 ki te \frac{1}{400} mā te whakarea 45 ki te tau huripoki o \frac{1}{400}.

$$45\times 400$$

Whakareatia te 45 ki te 400, ka 18000.

$$18000$$

Tauwehe

$$2^{4}\times 3^{2}\times 5^{3}$$
