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 and mars expecter answer in scientific notation do not round your answer

1 answer

To find the difference in distance between Neptune and Mars from Earth, we can subtract the average distance from Earth to Mars from the distance from Earth to Neptune:

4.3514 x 10^9 km - 2.25 x 10^8 km

To subtract these values, we need to have the same exponent for the scientific notation. Therefore, we can convert 2.25 x 10^8 km to scientific notation:

2.25 x 10^8 km = 0.225 x 10^9 km

Now we can subtract:
4.3514 x 10^9 km - 0.225 x 10^9 km = 4.1264 x 10^9 km

Therefore, Neptune is approximately 4.1264 x 10^9 km farther from Earth than Mars.
