#4.73*10^9 #

Explanation:

#4.73*10^9#

Easy trick for scientific notation is to remember the first number (before the multiplication) has to be between 1 and 10, always. So you have #4 730 000 000# can't be #473.0# (too big), #47.3# (too big) but #4.73# fits right between 1 and 10, so that's good.

Then for the order of the 10 count how many leaps all the way to right from the decimal in this case there are 9 numbers after the decimal so it's to the ^9
