1. Move the decimal point: Start with 284.0 and move the decimal point to the left until you have a number between 1 and 10. In this case, you'll move it two places to get 2.84.

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

3. Write in scientific notation: The result is 2.84 x 10²
