Answer 2

There are five significant digits in both the values.

There are basically three rules on determining how many significant figures are in a number = Non-zero digits are always significant in all the cases. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant.
