Answer:

Significant figures include all the digits in a measurement that are known with certainty as well as the last digit, which is an approximation. All non-zero digits (1-9) are to be counted as significant. All zeros between non-zero digits are always significant. Both 3906 and 20.04 contain four significant digits.
