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.

The distance from Earth to Neptune is farther than the distance from Earth to Mars by 4.3514 x 10^9 km - 2.25 x 10^8 km = 4.1264 x 10^9 km.

To find out how much farther Neptune is from Earth than Mars, we need to subtract the distance from Mars from the distance from Neptune.

Distance from Earth to Mars: 2.25 x 10^8 km
Distance from Earth to Neptune: 4.3514 x 10^9 km

This can be calculated as:

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

To subtract the distances, we can subtract the coefficients (numbers) and keep the same base (10) and exponent:

(4.3514 - 0.225) x 10^9 km

Simplifying:

4.1264 x 10^9 km

Therefore, 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 average distance from Earth to Mars from the average distance from Earth to Neptune.

The average distance from Earth to Mars is 2.25 x 10^8 km.
The distance from Earth to Neptune is 4.3514 x 10^9 km.

To find the difference, we subtract the distance to Mars from the distance to Neptune:

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

When subtracting numbers in scientific notation, make sure the exponents are the same. To do that, we can express the distance to Mars in terms of 10^9 km:

(2.25 x 10^8 km) can be rewritten as (0.225 x 10^9 km)

Now we can do the subtraction:

(4.3514 x 10^9 km) - (0.225 x 10^9 km)

Subtracting the values in front:

4.3514 - 0.225 = 4.1264

And combining the exponents:

10^9 km
Now we have our answer:

4.1264 x 10^9 km

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