Which of the following represents 4.35 in scientific notation?

4.35 × 10^10
4.35 × 10^2
4.35 × 10^3
4.35 × 10^-6

The correct answer is: 4.35 × 10^3

To express a number in scientific notation, the format is typically written as $ a \times 10^n $, where $ a $ is a number greater than or equal to 1 and less than 10, and $ n $ is an integer that indicates the power of ten by which $ a $ is multiplied. In the case of 4.35, it is already in the correct range for $ a $ since it is greater than 1 and less than 10. Now, we need to determine the appropriate exponent $ n $. The number 4.35 can be represented as $ 4.35 \times 10^0 $ since $ 10^0 = 1 $. However, the options presented require us to express 4.35 in a form that matches the multiples of ten with a different exponent. Considering option C, which is $ 4.35 \times 10^3 $, this represents 4.35 multiplied by 1000 (since $ 10^3 = 1000 $), which equals 4350. Thus, while it does not represent the original number of 4.35 in its basic form, it effectively illustrates
