Solve 2pinI/r10^-7

$$\frac{ 2 \pi nI }{ r } { 10 }^{ -7 }$$

Evaluate

$$\frac{\pi In}{5000000r}$$

Solution Steps

Calculate 10 to the power of -7 and get \frac{1}{10000000}.

$$\frac{2\pi nI}{r}\times \frac{1}{10000000}$$

Multiply \frac{2\pi nI}{r} times \frac{1}{10000000} by multiplying numerator times numerator and denominator times denominator.

$$\frac{2\pi nI}{r\times 10000000}$$

Cancel out 2 in both numerator and denominator.

$$\frac{\pi In}{5000000r}$$

Differentiate w.r.t. n

$$\frac{\pi I}{5000000r}$$
