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.

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
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.
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.
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.
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.
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.
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
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.
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.
Find 0.078−(5.2×10−3) . Express your answer in scientific notation. Do not round your answer.
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.
0.078 - (5.2×10^-3)
0.078 - 0.0052 = 0.0728
Therefore, the answer in scientific notation is 7.28×10^-2.
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 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.
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.
