Which of the following is the correct answer for 556, 098,146 written as a single digit times a power of 10?
5x10 negative 8 or is it 6x10 negative 8

To express **556,098,146** in scientific notation as a single digit times a power of 10, follow these steps:

1. Move the decimal point so that there is **only one digit to the left** of the decimal point. For **556,098,146**, this would be written as:
   \[
   5.56098146 \times 10^8
   \]

2. Now, round this value to just **one significant digit**. Since the first digit is **5** and the second digit is **5** (which rounds the first digit up to 6), the number becomes approximately:
   \[
   6 \times 10^8
   \]

Therefore, the correct answer is **\(6 \times 10^8\)**.
