You asked:
Evaluate the expression: \(\frac{400}{20 \cdot {10}^{-4}}\)
MathBot Answer:
\[\frac{400}{20 \cdot {10}^{-4}} = 200000\]
\[\begin{aligned}\frac{400}{20 \cdot {10}^{-4}}& = 400 \cdot \frac{1}{20 \cdot \frac{1}{10^{4}}}\\& = 400 \cdot \frac{1}{\frac{20}{10000}}\\& = 400 \cdot \frac{1}{\frac{1}{500}}\\& = 200000\end{aligned}\]
