The calculation is:
6.25×10^6 - 4.73×10^6
= (6.25 - 4.73) × 10^6
= 1.52 × 10^6
Therefore, the answer in scientific notation to 2 decimal places is 1.52×10^6.
6.25×10^6 - 4.73×10^6
= (6.25 - 4.73) × 10^6
= 1.52 × 10^6
Therefore, the answer in scientific notation to 2 decimal places is 1.52×10^6.

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 minus distance from Earth to Mars:
4.3514×10^9 km - 2.25×10^8 km
This can be written as: (4.3514 - 0.225) × 10^9 km
Simplifying:
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 the difference between the high end and the low end of the range, we need to subtract the low end from the high end.
High end rate - Low end rate:
2.329×10^−2 cm/h - 6.849×10^−4 cm/h
This can be written as: (2.329 - 0.006849) × 10^−2 cm/h
Simplifying:
2.329 × 10^−2 cm/h - 0.006849 × 10^−2 cm/h
= 2.322151 × 10^−2 cm/h
Therefore, the difference between the high end and the low end of the range is 2.322151 × 10^−2 cm/h.
High end rate - Low end rate:
2.329×10^−2 cm/h - 6.849×10^−4 cm/h
This can be written as: (2.329 - 0.006849) × 10^−2 cm/h
Simplifying:
2.329 × 10^−2 cm/h - 0.006849 × 10^−2 cm/h
= 2.322151 × 10^−2 cm/h
Therefore, the difference between the high end and the low end of the range is 2.322151 × 10^−2 cm/h.
