1. Math 2-8: Warm-up

2. Math 2-8: Powers and Exponents
Objective: How to use powers and exponents in expressions

3. Vocabulary base – in a power, the number used as a factor.
exponent – in a power, the number of times the base is used as a factor.
power – numbers written using exponents (represent repeated multiplication).

4. How to write and read powers:
An expression like 2·2·2·2 can be written as the power 24.
The base is the number that is multiplied.
The exponent tells how many times the base is used as a factor. }
The number that is expressed using an exponent is called a power.
