Mga Hakbang ng Solution

I-multiply ang 0.2 at 0.02 para makuha ang 0.004.

$$\frac{0.004}{4\pi \times 10^{-7}\times 450\times 1000}$$

Kalkulahin ang 10 sa power ng -7 at kunin ang \frac{1}{10000000}.

$$\frac{0.004}{4\pi \times \frac{1}{10000000}\times 450\times 1000}$$

I-multiply ang 4 at \frac{1}{10000000} para makuha ang \frac{1}{2500000}.

$$\frac{0.004}{\frac{1}{2500000}\pi \times 450\times 1000}$$

I-multiply ang \frac{1}{2500000} at 450 para makuha ang \frac{9}{50000}.

$$\frac{0.004}{\frac{9}{50000}\pi \times 1000}$$

I-multiply ang \frac{9}{50000} at 1000 para makuha ang \frac{9}{50}.

$$\frac{0.004}{\frac{9}{50}\pi }$$
