Whakaoti i te (4pi*10^-7)(2)/(2pi)(10)

$$\frac{ (4 \pi \times { 10 }^{ -7 } )(2) }{ (2 \pi )(10) }$$

Aromātai

$$\frac{1}{25000000}=0.00000004$$

Ngā Upane Otinga

Me whakakore tahi te 2\times 2\pi i te taurunga me te tauraro.

$$\frac{2\times 10^{-7}}{5}$$

Tātaihia te 10 mā te pū o -7, kia riro ko \frac{1}{10000000}.

$$\frac{2\times \frac{1}{10000000}}{5}$$

Whakareatia te 2 ki te \frac{1}{10000000}, ka \frac{1}{5000000}.

$$\frac{\frac{1}{5000000}}{5}$$

Tuhia te \frac{\frac{1}{5000000}}{5} hei hautanga kotahi.

$$\frac{1}{5000000\times 5}$$

Whakareatia te 5000000 ki te 5, ka 25000000.

$$\frac{1}{25000000}$$

Tauwehe

$$\frac{1}{2 ^ {6} \cdot 5 ^ {8}} = 4 \times 10^{-8}$$
