Calculate 6.25×106−4.73×10^6 . Express your answer in scientific notation to 2 decimal places.
To find the difference between the high end and the low end of the range, we subtract the low end from the high end:
2.329×10^−2 cm/hr - 6.849×10^−4 cm/hr
To subtract numbers in scientific notation, we need the same exponent. So, we can rewrite the second number as:
2.329×10^−2 cm/hr - 0.06849×10^−2 cm/hr
Now we can subtract the numbers:
= 2.329 - 0.06849 × 10^−2 cm/hr
The answer is 2.26051 × 10^−2 cm/hr.
To subtract numbers in scientific notation, we must have the same exponent. So, let's express the first number in scientific notation:
6.25 × 10^6 - 4.73 × 10^6
= (6.25 - 4.73) × 10^6
= 1.52 × 10^6
Therefore, the answer is 1.52 × 10^6.
I dont wont the work just the answer
The answer is 1.52 × 10^6.
The average distance from Earth to Mars is 2.25×10^8 km, and the distance from Earth to Neptune is 4.3514×10^9 km. How much farther is Neptune from Earth than Mars? Express your answer in scientific notation. Do not round your answer.(1 point)
To find the difference in distance, we subtract the distance to Mars from the distance to Neptune:
4.3514×10^9 km - 2.25×10^8 km
To subtract numbers in scientific notation, we need the same exponent. So, we can rewrite the second number as:
4.3514×10^9 km - 0.225×10^9 km
Now we can subtract the numbers:
= 4.3514 - 0.225 × 10^9 km
The answer is 4.1264 × 10^9 km.
Just wont the answer not the work
The difference in distance between Neptune and Mars 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.
Find 0.078−(5.2×10−3) . Express your answer in scientific notation. Do not round your answer.(1 point)
=×10−2
To subtract numbers, we simply subtract the values:
0.078 - (5.2 × 10^-3)
After subtracting, we can express the answer in scientific notation by moving the decimal point to the correct position:
= 0.078 - 0.0052
= 0.0728
Expressing the answer in scientific notation, we have:
= 7.28 × 10^-2
Earth’s radius is approximately 3,959 miles, while Jupiter’s radius is approximately 4.3441×10^4 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 how much bigger Jupiter's radius is compared to Earth's, we subtract Earth's radius from Jupiter's radius:
4.3441×10^4 miles - 3,959 miles
To subtract these numbers, we first convert Earth's radius to scientific notation:
3,959 miles = 3.959×10^3 miles
Now we can subtract the numbers:
= 4.3441×10^4 miles - 3.959×10^3 miles
To subtract numbers in scientific notation, we need to have the same exponent. So, we can rewrite Earth's radius as:
4.3441×10^4 miles - 0.3959×10^4 miles
Now we can subtract the numbers:
= 3.9482×10^4 miles
Therefore, Jupiter's radius is 3.9482 × 10^4 miles bigger than Earth's radius.

−4.5866×10−5
To subtract the numbers in scientific notation, we need to have the same exponent. So, let's rewrite the numbers with the same exponent:
4.66×10^-5 - 7.34×10^-7
= 4.66×10^-5 - 0.734×10^-5
Now we can subtract the numbers:
= (4.66 - 0.734) × 10^-5
= 3.926 × 10^-5
Therefore, the answer is 3.926 × 10^-5.
