1. Move the decimal point:

* Start with 372. The decimal point is understood to be at the end (372.).

* Move the decimal point to the left until you have a number between 1 and 10. You'll need to move it two places to get 3.72.

2. Count the decimal places:

* You moved the decimal point two places to the left.

3. Express in scientific notation:

* The number becomes 3.72

* Since you moved the decimal two places to the left, the exponent is positive 2.

* The final answer is 3.72 x 10²
