Tohaina
Kua tāruatia ki te papatopenga
\frac{0.004}{4\pi \times 10^{-7}\times 450}
Whakareatia te 0.2 ki te 0.02, ka 0.004.
\frac{0.004}{4\pi \times \frac{1}{10000000}\times 450}
Tātaihia te 10 mā te pū o -7, kia riro ko \frac{1}{10000000}.
\frac{0.004}{\frac{1}{2500000}\pi \times 450}
Whakareatia te 4 ki te \frac{1}{10000000}, ka \frac{1}{2500000}.
\frac{0.004}{\frac{9}{50000}\pi }
Whakareatia te \frac{1}{2500000} ki te 450, ka \frac{9}{50000}.
