The average distance from earth to mars is 2.25 x 10^8 km, and the distance from earth to Neptune is 4.3514 x 10^9 km. How much farther is Neptune from earth than mars? Express your answer in scientific notation. Do not round your answer
To find out how much farther Neptune is from Earth than Mars, we need to subtract the distance between Earth and Mars from the distance between Earth and Neptune.
Distance between Earth and Neptune: 4.3514 x 10^9 km
Distance between Earth and Mars: 2.25 x 10^8 km
Subtracting the distance between Earth and Mars from the distance between Earth and Neptune:
4.3514 x 10^9 km - 2.25 x 10^8 km
To subtract the values, we need to express them in the same exponent form, so let's convert the distance between Mars and Earth to 10^9 km:
2.25 x 10^8 km = 0.225 x 10^9 km
Now, we can subtract the distances:
4.3514 x 10^9 km - 0.225 x 10^9 km = 4.1264 x 10^9 km
So, Neptune is 4.1264 x 10^9 km farther from Earth than Mars.
To find out 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.
Distance from Earth to Mars: 2.25 x 10^8 km
Distance from Earth to Neptune: 4.3514 x 10^9 km
Neptune's distance - Mars's distance = 4.3514 x 10^9 km - 2.25 x 10^8 km
To subtract these values, we need to align the decimal points by multiplying the distance to Mars by 10.
2.25 x 10^8 km = 0.225 x 10^9 km
Now we have:
4.3514 x 10^9 km - 0.225 x 10^9 km
Subtracting the decimal part:
4.3514 x 10^9 km - 0.225 x 10^9 km = 4.1264 x 10^9 km
Therefore, Neptune is 4.1264 x 10^9 km farther than Mars from Earth.
To find out how much farther Neptune is from Earth than Mars, we need to subtract the distance from Mars to Earth from the distance from Neptune to Earth.
The distance from Earth to Mars is given as 2.25 x 10^8 km.
The distance from Earth to Neptune is given as 4.3514 x 10^9 km.
To subtract these two distances, we subtract the distance to Mars from the distance to Neptune:
4.3514 x 10^9 km - 2.25 x 10^8 km = 4.3514 x 10^9 km - 0.225 x 10^9 km
To simplify the calculation, we need to convert both distances to the same power of 10. In this case, we can convert the distance to Mars to 10^9 km:
2.25 x 10^8 km = 0.225 x 10^9 km
Now we can subtract the distances:
4.3514 x 10^9 km - 0.225 x 10^9 km = 4.1264 x 10^9 km
So, Neptune is approximately 4.1264 x 10^9 km farther from Earth than Mars.
