To find the difference in distance between Neptune and Mars, we need to subtract the distance from Earth to Mars from the distance from Earth to Neptune.
The distance from Earth to Mars is 2.25x10^8 km.
The distance from Earth to Neptune is 4.3514x10^9 km.
Therefore, the difference in distance is 4.3514x10^9 km - 2.25x10^8 km.
To subtract the two distances, we can write both distances in scientific notation with the same exponent by moving the decimal point in 2.25x10^8 km one place to the right:
2.25x10^8 km = 2.25x10^9 km x 10^(-1).
Now we can subtract the two distances:
4.3514x10^9 km - 2.25x10^9 km x 10^(-1).
= 4.3514x10^9 km - 2.25x10^9 km x 10^(-1).
= 4.3514x10^9 km - 2.25x10^9 km x 10^(-1).
= 43.514x10^8 km - 2.25x10^9 km.
= 43.514x10^8 km - 2.25x10^9 km.
= (43.514 - 2.25)x10^9 km.
= 41.264x10^9 km.
Therefore, Neptune is 4.1264x10^10 km farther from Earth than Mars.
A average distance from Earth to Mars is 2.25x10^8 km, and the distance from Earth to Neptune is 4.3514x10^9 km. How much farther is Neptune from Earth than Mars? Express your answer in scientific notation. Do not round your answer.
