This document contains notes from a lesson on exponential notation. It includes examples of using exponential notation to write very large and small numbers, and discusses the rules for when the result of a negative number raised to a power will be positive or negative depending on whether the power is even or odd. The summary reviews the key points that exponential notation is used to efficiently write scientific quantities, and that a negative base must be in parentheses when using exponents.

The product is positive. When a negative number is raised to an
EVEN power, the result is always POSITIVE.
The product is negative. When a negative number is
raised to an ODD power, the result is always NEGATIVE.
Hmmm...

No, a negative number to an ODD power will always result in a negative
product.
No, a negative number to an EVEN power will always result in a positive
product.

Josie is incorrect. The base should be written as (-15).
When the base is a negative number, the base must be
written in parenthesis.

Questions to think about...
The sign is always negative.
The sign is always positive.
*Reminder: When the base is negative, it must always be
written in parenthesis.*

Why should we bother with exponential notation?
Exponential notation saves writing!!!!
Exponential notation is used for recording
scientific measures of very large or very small
quantities.
