To find the difference between the distances from Earth to Neptune and Mars, we subtract the distance from Mars from the distance from Neptune:
(4.3514 * 10^9 km) - (2.25 * 10^8 km)
To subtract the numbers in scientific notation, we should have the same exponent. So, we need to convert the distance from Mars into scientific notation:
2.25 * 10^8 km = 0.225 * 10^9 km
Now, we can subtract:
(4.3514 * 10^9 km) - (0.225 * 10^9 km) = (4.3514 - 0.225) * 10^9 km
Simplifying the subtraction:
4.1264 * 10^9 km
Therefore, Neptune is approximately 4.1264 * 10^9 km further from Earth than Mars.
the average distance from Earth to Mars is 2.25 x 10^8 km and the distance from Earth to Neptune is 4.3514 * 10 ^ 9 km how much further is Neptune from Earth than Mars express your answer in scientific notation
