I'm wondering how you determine the number of significant figures of a number in scientific notation with trailing zeros.
(which is not in correct scientific notation) has how many significant figures?
On first guess you would say the number has 5 sigfigs because it has a decimal point, but in reality, that decimal point just helps indicate magnitude. All trailing zeroes can be removed and the number changed to
Now the number has only 2 significant figures.
Which answer is correct: 2 or 5? Can someone please clarify this
