Here's how to get there:
1. Move the decimal point: Start with 108,000,000. Move the decimal point 8 places to the left until you have a number between 1 and 10 (which is 1.08).
2. Count the moves: You moved the decimal point 8 places.
3. Express as a power of 10: Since you moved the decimal to the *left*, the power of 10 is positive.
Therefore, 108,000,000 in scientific notation is 1.08 x 10⁸.
