6.25×10^6 - 4.73×10^6 can be calculated by subtracting the coefficients (6.25 - 4.73) and keeping the same exponent (10^6).

This gives us: 6.25 - 4.73 = 1.52

Therefore, the answer in scientific notation to 2 decimal places is 1.52×10^6.

To calculate 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.

4.3514×10^9 km - 2.25×10^8 km

Next, we can subtract the coefficients while keeping the same exponent:

4.3514 - 2.25 = 2.1014

Therefore, the answer in scientific notation is 2.1014×10^9 km.

To find out how much farther Neptune is from Earth than Mars, we need to subtract the distance to Mars from the distance to Neptune:

4.3514×10^9 km - 2.25×10^8 km

Performing the subtraction while keeping the same exponent:

4.3514 - 0.225 = 4.1264

Therefore, the answer in scientific notation is 4.1264×10^9 km.

To find the difference between the high end (2.329×10^(-2) cm/h) and the low end (6.849×10^(-4) cm/h) of the range, we subtract the low end from the high end:

2.329×10^(-2) cm/h - 6.849×10^(-4) cm/h

Performing the subtraction while keeping the same exponent:

2.329 - 0.006849 = 2.322151

Therefore, the difference between the high end and the low end of the range, expressed in scientific notation, is 2.322151×10^(-2) cm/h.

To subtract (5.2×10^-3) from 0.078, we can perform the subtraction normally:

0.078 - (5.2×10^-3)

0.078 - 0.0052 = 0.0728

Therefore, the answer in scientific notation is 7.28×10^-2.

To find out how much bigger Jupiter's radius is compared to Earth's, we need to subtract the Earth's radius from Jupiter's radius:

4.3441×10^4 miles - 3,959 miles

Next, we can subtract the numbers while keeping the same exponent:

43,441 - 3,959 = 39,482

Therefore, the answer in scientific notation is 3.9482×10^4 miles.
