In that case, the inverse square law is all you'd need. Flavorflav was assuming that it was asking for the difference in astronomical magnitudes which is also be a reasonable question, but he took the log base 10, despite the fact that magnitudes correspond to a factor of about 2.51, not 10, so you'd need to take the log base 2.51.

Thank you for any feedback.
