The average distance from earth to mars is 2.25 times 10^8 km, and the distance from earth to neptune is 4.3514 time 10^9 km. how much farther is neptune from earth then mars. express your answer in scientific notation. do not round your answer

Answer 1

To find 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

Difference in distance = (4.3514 × 10^9) km - (2.25 × 10^8) km

We can subtract the distances by subtracting the coefficients and keeping the larger power of 10:

4.3514 - 2.25 = 2.1014

Since the power of 10 in the larger distance (4.3514 × 10^9 km) is 9, the answer is:

2.1014 × 10^9 km
