The average distance from Earth to Mars is 2.25×10^8 km, and the distance from Earth to Neptune is 4.3514×10^9 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 the difference in distance between Neptune and Mars, we subtract the distance to Mars from the distance to Neptune:
4.3514×10^9 km - 2.25×10^8 km
We can subtract these numbers directly, and keep the result in scientific notation:
4.3514×10^9 km - 2.25×10^8 km = 4.3514×10^9 - 2.25×10^8 = 4.3514×10^9 - 0.225×10^9 = 4.3514×10^9 - 0.225×10^9 = 4.1264×10^9
So 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 Neptune - Distance from Earth to Mars
= (4.3514×10^9 km) - (2.25×10^8 km)
To subtract these quantities in scientific notation, we need to ensure that the exponents are the same. Since the exponent for 10^8 is smaller than the exponent for 10^9, we can convert the distance from Earth to Mars into scientific notation with an exponent of 9:
= (4.3514×10^9 km) - (0.225×10^9 km)
Now, we can subtract the distances:
= 4.3514 - 0.225 = 4.1264
Since the exponent for both the distances is 9, the answer will also have an exponent of 9:
= 4.1264×10^9 km
Therefore, Neptune is approximately 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.
The distance from Earth to Mars is 2.25×10^8 km, and the distance from Earth to Neptune is 4.3514×10^9 km.
So, the calculation will be:
Distance from Earth to Neptune - Distance from Earth to Mars = Answer
(4.3514×10^9 km) - (2.25×10^8 km)
To subtract numbers written in scientific notation, we need to make sure the exponents are the same.
In this case, we have 10^9 km and 10^8 km. To make the exponents the same, we can rewrite 10^8 km as 1×10^9 km.
So, our calculation becomes:
(4.3514×10^9 km) - (2.25×10^8 km) = (4.3514×10^9 km) - (0.225×10^9 km)
Now, we can subtract the numbers:
(4.3514 - 0.225) × 10^9 km = 4.1264 × 10^9 km
Therefore, Neptune is 4.1264 × 10^9 km farther from Earth than Mars.
