Mercury is about 57,000,000 from the sun, whereas neptune is about 4.5 x 10 to the 9th power km from the sun. What is the difference between mercury and neptune's distance from the sun

4,443,000,000 or 4.443 * 10^9 km.

Step-by-step explanation:

Neptune's distance from the sun = 4.5 * 10^9

= 4,500,000,000 km.

The required difference is

4,500,000,000 - 57,000,000

= 4,443,000,000 or 4.443 * 10^9.
