Based upon the 2010 census data, the total population of the U.S. is 308,745,538people, approximately what is this population in scientific notation?
3.1 x 10^8
3.1 x 10^7
3.1 x 10^-8 My answer.
31 x 10 ^ 7
So the answer is A?
the exponent should be positive , not negative
thx
Yea careful with the exponent. 3.1*10^-8 would be significantly smaller than 3.1*10^8.
just give the answer bro
To express a number in scientific notation, you need to move the decimal point so that there is only one non-zero digit to the left of it. In this case, the original population is 308,745,538.
To convert this number to scientific notation:
1. Start by moving the decimal point after the first non-zero digit, which is 3.
- The number becomes 3.08745538.
2. Count the number of places you moved the decimal point. In this case, 8 places.
3. Rewrite the number as a decimal with one digit before the decimal point.
- 3.08745538 becomes 3.08745538.
4. Finally, express the number in scientific notation by multiplying it by 10 raised to the power of the number of places you moved the decimal point (8 in this case).
- 3.08745538 x 10^8
So the population of the U.S. in scientific notation is approximately 3.1 x 10^8.
