How is 4,325 represented in scientific notation?

4.325 × 10^3
4.325 × 10^2
4.325 × 10^4
4.325 × 10^1

The correct answer is: 4.325 × 10^3

To represent a number in scientific notation, it should be expressed as a product of a number between 1 and 10 and a power of ten. In the case of 4,325, the first step is to move the decimal point so that the number falls between 1 and 10. Moving the decimal point two places to the left gives us 4.325. Next, we need to account for the movement of the decimal point by using a power of ten. Since we moved the decimal point two places to the left, we multiply by 10 raised to the power of 3 (because 10^3 equals 1,000, and 4.325 multiplied by 1,000 equals 4,325). Thus, the correct representation of 4,325 in scientific notation is 4.325 × 10^3. This formulation accurately reflects the original number while adhering to the conventions of scientific notation.
