The average distance from earth to Mars is 2.25×10⁸ km, and the distance from earth to Neptune is 4.3514×10⁹ 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 subtract the distance from Earth to Mars from the distance from Earth to Neptune.
Distance from Earth to Neptune - Distance from Earth to Mars
= 4.3514×10⁹ km - 2.25×10⁸ km
= 4.3514×10⁹ km - 0.225×10⁹ km
= (4.3514 - 0.225)×10⁹ km
= 4.1264×10⁹ km
So, Neptune is 4.1264×10⁹ km farther from Earth than Mars.
To find how much farther Neptune is from Earth than Mars, we need to calculate the difference between their distances.
The distance from Earth to Mars is 2.25×10⁸ km, and the distance from Earth to Neptune is 4.3514×10⁹ km.
To find the difference, we subtract the distance to Mars from the distance to Neptune:
4.3514×10⁹ km - 2.25×10⁸ km
This gives us 4.3514×10⁹ km - 2.25×10⁸ km = (4.3514 - 0.225) × 10⁹ km = 4.1264 × 10⁹ km.
Therefore, Neptune is 4.1264 × 10⁹ km farther from Earth than Mars.
To find out how much farther Neptune is from Earth than Mars, we need to calculate the difference between the distances.
First, let's subtract the distance from Earth to Mars from the distance from Earth to Neptune:
4.3514×10⁹ km - 2.25×10⁸ km
To subtract numbers in scientific notation, we need to make sure the exponents are the same. In this case, we can rewrite 2.25×10⁸ km as 2.25×10⁹ km (by padding it with a zero), so now both numbers have the same exponent:
4.3514×10⁹ km - 2.25×10⁹ km
Now, we can subtract the numbers:
(4.3514 - 2.25) × 10⁹ km
The result of the subtraction is:
2.1014×10⁹ km
Therefore, Neptune is 2.1014×10⁹ km farther from Earth than Mars.
