1. Understand the Conversion:

* There are 100 centimeters (cm) in 1 meter (m).

2. Convert to Meters:

* Divide 28.4 cm by 100: 28.4 cm / 100 = 0.284 m

3. Express in Scientific Notation:

* Scientific notation is written as a number between 1 and 10 multiplied by a power of 10.

* Move the decimal point two places to the right: 0.284 becomes 2.84

* Since we moved the decimal two places to the right, the power of 10 is -2.

Therefore, 28.4 cm in scientific notation is 2.84 x 10⁻² m
