Whakaoti i te =2(10^-4)+6(10^-8)/1+3(10^-4)

$$= \frac { 2 ( 10 ^ { - 4 } ) + 6 ( 10 ^ { - 8 } ) } { 1 + 3 ( 10 ^ { - 4 } ) }$$

Aromātai

$$\frac{1}{5000}=0.0002$$

Ngā Upane Otinga

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

$$\frac{2\times \frac{1}{10000}+6\times 10^{-8}}{1+3\times 10^{-4}}$$

Whakareatia te 2 ki te \frac{1}{10000}, ka \frac{1}{5000}.

$$\frac{\frac{1}{5000}+6\times 10^{-8}}{1+3\times 10^{-4}}$$

Tātaihia te 10 mā te pū o -8, kia riro ko \frac{1}{100000000}.

$$\frac{\frac{1}{5000}+6\times \frac{1}{100000000}}{1+3\times 10^{-4}}$$

Whakareatia te 6 ki te \frac{1}{100000000}, ka \frac{3}{50000000}.

$$\frac{\frac{1}{5000}+\frac{3}{50000000}}{1+3\times 10^{-4}}$$

Tāpirihia te \frac{1}{5000} ki te \frac{3}{50000000}, ka \frac{10003}{50000000}.

$$\frac{\frac{10003}{50000000}}{1+3\times 10^{-4}}$$

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

$$\frac{\frac{10003}{50000000}}{1+3\times \frac{1}{10000}}$$

Whakareatia te 3 ki te \frac{1}{10000}, ka \frac{3}{10000}.

$$\frac{\frac{10003}{50000000}}{1+\frac{3}{10000}}$$

Tāpirihia te 1 ki te \frac{3}{10000}, ka \frac{10003}{10000}.

$$\frac{\frac{10003}{50000000}}{\frac{10003}{10000}}$$

Whakawehe \frac{10003}{50000000} ki te \frac{10003}{10000} mā te whakarea \frac{10003}{50000000} ki te tau huripoki o \frac{10003}{10000}.

$$\frac{10003}{50000000}\times \frac{10000}{10003}$$

Whakareatia te \frac{10003}{50000000} ki te \frac{10000}{10003}, ka \frac{1}{5000}.

$$\frac{1}{5000}$$

Tauwehe

$$\frac{1}{2 ^ {3} \cdot 5 ^ {4}} = 0.0002$$
