Mercury is 5.8 * 10 ^ 7 km from the sun. Neptune is 4.5 * 10 ^ 10 km from the sun. How much further is Neptune from the sun than Mercury? (1 point)

Divide the distances: (4.5 * 10 ^ 19)/(5.8 * 10 ^ 7) = 0.78 * 10 ^ 3 = 7.8 * 10 ^ 2 * km

Add the distances together. (5.8 * 10 ^ 7) + (4.5 * 10 ^ 10) = 10.3 * 10 ^ 17 = 1.03 * 10 ^ 18 * km

Subtract the distances by getting the same power of 10

(4.5 * 10 ^ 10) - (5.8 * 10 ^ 7) = (4.5 * 10 ^ 10) - (0.0058 * 10 ^ 10) = 4.49 * 10 ^ 10 * k

Multiply the distances: (5.8 * 10 ^ 7)(4.5 * 10 ^ 10) = (5.8 * 4.5)(10 ^ (7 + 10)) = 26.1 * 10 ^ 17 = 2.61 * 10 ^ 16 * kT

Neptune is 1.03 * 10^18 km further from the sun than Mercury.
