To Divide using Scientific Notation:

Divide decimal numbers with each other.
Use exponent rules to "combine" powers of 10.
If the answer is not in "correct" scientific notation, change to correct notation.

Example:
8.8 x 10⁵ / 2.2 x 10²
= (8.8/2.2) x 10^5-2 (Law of indicies: a^m/aⁿ = a^m-n)
=4.0 x 10³

Directions: Divide the following numbers written in scientific notation and choose the correct answer. Also write atleast 5 examples of your own.
