Here's how to convert it:

1. Move the decimal point: Start with 13,000,000,000. Move the decimal point to the left until you have a number between 1 and 10 (in this case, 1.3).

2. Count the moves: You moved the decimal point 10 places to the left.

3. Express as a power of 10: Since you moved the decimal to the left, the power of 10 is positive.

Therefore, 13,000,000,000 in scientific notation is 1.3 x 10^10.
