The average distance from earth to mars is 2.25x10^8km, And the distance from earth to neptune is 4.3514x10^9km. 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 need to subtract the average distance from Earth to Mars from the average distance from Earth to Neptune.
Distance difference = Distance from Earth to Neptune - Distance from Earth to Mars
Distance difference = (4.3514x10^9km) - (2.25x10^8km)
Now, let's subtract the values:
Distance difference = 4.3514x10^9km - 2.25x10^8km
To subtract these values, we need to have them in the same exponent form. Let's rewrite 2.25x10^8km as 0.225x10^9km:
Distance difference = 4.3514x10^9km - 0.225x10^9km
Now we can subtract the values in front of the exponential term:
Distance difference = 4.3514 - 0.225 = 4.1264
The answer can be expressed in scientific notation as:
Distance difference = 4.1264x10^9 km
So, Neptune is 4.1264x10^9 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 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:
(4.3514 × 10^9 km) - (2.25 × 10^8 km)
To perform the subtraction, we need to express the numbers in the same power of 10:
(4.3514 × 10^9 km) - (0.225 × 10^9 km) in scientific notation
Simplifying the subtraction:
4.3514 × 10^9 km - 0.225 × 10^9 km = 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.
Given:
Distance from Earth to Mars: 2.25x10^8 km
Distance from Earth to Neptune: 4.3514x10^9 km
Subtracting the distance to Mars from the distance to Neptune:
4.3514x10^9 km - 2.25x10^8 km
To subtract these values, we need to align the exponents, which means converting 2.25x10^8 km into scientific notation with an exponent of 9 (same as Neptune's distance).
2.25x10^8 km = 2.25x10^8 km x 10^1 = 2.25x10^9 km
Now we can subtract:
4.3514x10^9 km - 2.25x10^9 km = 2.1014x10^9 km
Therefore, Neptune is 2.1014x10^9 km farther from Earth than Mars.
