The distance from Earth to Mars is 2.25×10⁸ km.
The distance from Earth to Neptune is 4.3514×10⁹ km.
To find how much farther Neptune is from Earth than Mars, we need to subtract the distance from Earth to Mars from the distance from Earth to Neptune.
Thus, the difference is:
4.3514×10⁹ km - 2.25×10⁸ km = 4.3514×10⁹ - 2.25×10⁸
= 42.8635×10⁸ km
However, we need to express the difference in scientific notation. So let's write 42.8635 in scientific notation:
42.8635 = 4.28635×10
Therefore, the difference in distance is 4.28635×10 x 10⁸ km in scientific notation.
The average distance from earth to Mars is 2.25×10⁸ km, and the distance from earth to Neptune is 4.3514×10⁹ km. How much farther is Neptune from earth than Mars? Express your answer in scientific notation. Do not round your answer.
