miles from Earth. How much farther is the Sun than the Moon from Earth

Answer 1

Distance difference = 9.29×10^7 − 2.389×10^5 miles.

Write the moon's distance with the same exponent: 2.389×10^5 = 0.02389×10^7.

So 9.29×10^7 − 0.02389×10^7 = (9.29 − 0.02389)×10^7 = 9.26611×10^7 miles.

In standard form: 92,661,100 miles (≈ 9.27×10^7 miles).
