Significant figures are all the digits excluding leading zeros for small decimals and zeros at the end of an integer.
45.030 has 5 significant figures because the zero at the end is after the decimal point. This means that the number was measured with 3 decimal places of precision. If the last zero was not significant, the number would be written 45.03.
On the other hand, 45030 only has 4 significant figures. Hope this helps!

We'll make this a bit simpler.
1 mile = 1.60934km
90.0 million miles.
9.0 x 10^7 miles * (1.60934km / 1 mile) * (1000m / 1km) = 7.70x10^79 m
