The average distance from earth to Mars is 2.25x10^8km and the distance from earth to Neptune is 4.3514x10^9km how much further is Neptune from earth than mars express your answer in scientific notation do not round your answer

Answer 1

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:

4.3514x10^9 km - 2.25x10^8 km

To subtract these values, we need to express both distances in the same power of 10. Let's convert the distance from Earth to Mars to 10^9:

2.25x10^8 km = 0.225x10^9 km

Now we can subtract:

4.3514x10^9 km - 0.225x10^9 km

This gives us the result of:

4.1264x10^9 km

Therefore, Neptune is 4.1264x10^9 km further from Earth than Mars.
