Whakaoti i te 1000*10^-6-7*10^-4

$$1000 \times { 10 }^{ -6 } -7 \times { 10 }^{ -4 }$$

Aromātai

$$\frac{3}{10000}=0.0003$$

Ngā Upane Otinga

Tātaihia te 10 mā te pū o -6, kia riro ko \frac{1}{1000000}.

$$1000\times \frac{1}{1000000}-7\times 10^{-4}$$

Whakareatia te 1000 ki te \frac{1}{1000000}, ka \frac{1}{1000}.

$$\frac{1}{1000}-7\times 10^{-4}$$

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

$$\frac{1}{1000}-7\times \frac{1}{10000}$$

Whakareatia te 7 ki te \frac{1}{10000}, ka \frac{7}{10000}.

$$\frac{1}{1000}-\frac{7}{10000}$$

Tangohia te \frac{7}{10000} i te \frac{1}{1000}, ka \frac{3}{10000}.

$$\frac{3}{10000}$$

Tauwehe

$$\frac{3}{2 ^ {4} \cdot 5 ^ {4}} = 0.0003$$
