1. Identify the decimal place: The decimal point is currently at the end of the number (384401).
2. Move the decimal point to create a number between 1 and 10: Move the decimal point five places to the left: 3.84401
3. Count the number of places moved: You moved the decimal point 5 places to the left.
4. Express the number in scientific notation:
* The number becomes 3.84401
* Since you moved the decimal to the left, the exponent is positive.
* The exponent is the number of places you moved the decimal (5)
Therefore, the average distance from Earth to the Moon in scientific notation is 3.84401 x 10⁵ km.
