*Solving Exponents and Powers*

#### Intro

We know how to solve the problem 5 x 5. This expression can be written in a shorter way, using something called *exponents*.

5 x 5 = 5^2

An expression that represents a repeated multiplication of the same number is called a *power*.

The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.

#### Sample Problem

Evaluate the problem: 3^2 x 4 = ?

#### Solution

1) Using PEMDAS (parenthesis, exponent, multiply, divide, add, subtract), first solve the exponents: 3×3 = 9

2) Rewrite: 9 x 4 = ?

3) Solve: 36
