For every decimal place that you move over, add one to the exponent of the 10.

So in this problem, you would move nine spaces to the left, so the exponent above the 10 would be a nine. 

Therefore, the scientific notation would be:
4.4982529 x 10^9

4,498,252,900 in scientific notation
=
4.4982529 x 10^9

hope it helps
