Calculate 6.25×106−4.73×106 . Express your answer in scientific notation to 2 decimal places.

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 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 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.

The average distance from Earth to Mars is 2.25×108 km, and the distance from Earth to Neptune is 4.3514×109 km. How much farther is Neptune from Earth than Mars? Express your answer in scientific notation. Do not round your answer. km

The average distance from Earth to Mars is 2.25×108 km, and the distance from Earth to Neptune is 4.3514×109 km. How much farther is Neptune from Earth than Mars? Express your answer in scientific notation. Do not round your answer.

Human hair grows at a rate of about 6.849×10−4 cm per hour to 2.329×10−2 cm per hour. The rate depends on gender, genetics, age, and health. Find the difference between the high end and the low end of the range. Express your answer in scientific notation. Do not round your answer

Find 0.078−(5.2×10−3) . Express your answer in scientific notation. Do not round your answer.

Earth’s radius is approximately 3,959 miles, while Jupiter’s radius is approximately 4.3441×104 miles. How much bigger is Jupiter’s radius compared to Earth’s? Express your answer in scientific notation. Do not round your answer.

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.
