#4# significant digits

Explanation:

#60.02# is a sequence of 4 significant digits

(the length of a sequence of significant digits begins with the first non-zero digit and ends with the last non-zero digit).

The #10^5# is simply a scaling factor that has no effect on the number of significant digits.

#color(red)(6,002) xx 10^5 # has 4 significant figures.

Explanation:

This would be easier to see if we wrote it out in full first.

#60.02 xx10^5 = 6,002,000#

#color(red)(6,002),000 # has 4 significant figures.

#color(red)(6,002) xx 10^5 # also has 4 significant figures.
