# Introduction to Applying Exponent Rules

## What you'll learn to do: Simplify expressions using properties of exponents

In this section we will learn how to simplify and perform mathematical operations such as multiplication and division on terms that have exponents. We will also learn how to use scientific notation to represent very large or very small numbers, and perform mathematical operations on them. Specifically, in this section you’ll learn how to:- Evaluate exponential expressions
- Simplify expressions using the Product Property of Exponents
- Simplify expressions using the Power Rule of Exponents
- Simplify expressions using the Product to a Power Property
- Simplify expressions using the Quotient Properties of Exponents
- Simplify exponential expressions containing negative exponents and exponents of 0 and 1
- Simplify complex expressions using a combination of exponent rules
- Simplify compound expressions using a combination of exponent rules

If you missed this problem, review the following example.
Answer: Solution

[latex]{3}^{4}[/latex] | |

Expand the expression. | [latex]3\cdot 3\cdot 3\cdot 3[/latex] |

Multiply left to right. | [latex]9\cdot 3\cdot 3[/latex] |

[latex]27\cdot 3[/latex] | |

Multiply. | [latex]81[/latex] |

Simplify:
[latex-display]-7-\left(-4\right)\text{ and }-7+4[/latex-display]

Answer: Solution:

[latex]-7-\left(-4\right)[/latex] and [latex]-7+4[/latex] | |

Subtract to simplify. | [latex]-7-\left(-4\right)=-3[/latex] |

Add to simplify. | [latex]-7+4=-3[/latex] |

Subtracting [latex]−4[/latex] from [latex]−7[/latex] is the same as adding [latex]4[/latex] to [latex]−7[/latex]. |
