#### Explanation:

You need to write your number as a power of $10$; you need to move the decimal point to the right up to pass the first non-zero digit using the number of movements of the point as power:

$- \to$
$5.0210 \times {10}^{- \text{number of movements}}$

giving: $5.021 \times {10}^{-} 4$
