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.(1 point)
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 distance from Earth to Neptune.
4.3514×10^9 km - 2.25×10^8 km
In order to subtract these two numbers, we need to align the decimal points by moving the decimal point one place to the right in the first number.
43.514×10^8 km - 2.25×10^8 km
Now we can subtract the two numbers:
43.514×10^8 km - 2.25×10^8 km = 41.264×10^8 km
Finally, we can express the answer in scientific notation by moving the decimal point one place to the left:
4.1264×10^9 km
Therefore, Neptune is 4.1264×10^9 km farther from Earth than Mars.
To find out how much farther Neptune is from Earth than Mars, we need to subtract the distance from Earth to Mars from the distance from Earth to Neptune.
Distance from Earth to Mars = 2.25 × 10^8 km
Distance from Earth to Neptune = 4.3514 × 10^9 km
Subtracting the distance to Mars from the distance to Neptune, we have:
(4.3514 × 10^9 km) - (2.25 × 10^8 km)
To subtract the distances, we need to have the same power of 10. We can rewrite 2.25 × 10^8 km as 0.225 × 10^9 km.
Now we can subtract the distances:
(4.3514 × 10^9 km) - (0.225 × 10^9 km)
Simplifying, we have:
4.3514 × 10^9 km - 0.225 × 10^9 km = 4.1264 × 10^9 km
Therefore, Neptune is 4.1264 × 10^9 km farther from Earth than Mars.
To find 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:
4.3514×10^9 km - 2.25×10^8 km
To subtract these numbers in scientific notation, we need to ensure that the exponents are in the same power of 10.
To do this, we can express the distance to Mars in scientific notation with the same exponent as Neptune:
2.25×10^8 km = 2.25×10^8 km × 10^1 = 2.25×10^9 km
Now that the exponents are the same, we can subtract the distances:
(4.3514×10^9 km) - (2.25×10^9 km) = 2.1014×10^9 km
Therefore, Neptune is 2.1014×10^9 km farther from Earth than Mars.
