Question

When 8982 rounded to 2 significant figures, the answer is 9000. But according to the rule, if a number does not have a decimal, then don't count the zero after the last non-zero digit, which in this is 9. So according to me, 9000 only has 1 significant figure, but as for the question, it says round 8982 to two significant figures and the answer is 9000, and they include the first zero after 9 as significant. Can someone help?
