# Multiplying Monomials

Multiplying monomials requires that you understand and can apply the
laws of exponents. Let's quickly review the laws of exponents that will
be needed.

## Laws of Exponents

**Multiplying Powers with the Same Base** - Add the exponents. For example: ( a^{3 }) (a^{2}) = a^{5}

**Power of a Power** - Multiply the exponents. For example: (a^{3})^{5} = a^{15}

**Power of a Product** -find the power of each factor and multiply. For example: (3a)^{2} = 9a^{2}

## When you multiply monomials, you will need to perform two steps:

- Multiply the coefficients (Numbers)

- Multiply the variables. (Use the laws of exponents when necessary)

Let's look at a few examples.

Each line of these examples shows a different step.

I broke it down
step by step for you to see the exact process. You will be able to do
a lot of this work mentally, which I will show you later on.

I wanted
you to understand each step, that's why these explanations are so long.

This first example shows how you use **multiplying powers with the same base** in order to multiply monomials.

## Example 1: Multiplying Powers with the Same Base

This second example will utilize the **Power of a Product** property in order to simplify the expression.

## Example 2: Using Power of a Product

One more example, but this time I'm not going to show each individual
step. As you master this skill, this is the way in which you will
multiply monomials. It's actually pretty quick!
