Outcomes
By the end of this lesson you will be able to answer questions like the ones in the pre-test below.
First answer the questions on the pre-test below in your Math 3103 binder. Then refer to the pages of the lesson that contain instruction on the questions for which you get an incorrect answer or for which you would like some further explanation.
Alternately, you can proceed directly to the first page of the lesson without doing the pre-test. To do this simply click on the Lesson button above. You can then return to this pre-test and use it as a worksheet.
Pre-test
Express each of the following in simplest form without exponents:
1. 20 2. 3-2 3. 
4. 6-2 x 50
5. 6(5 - 2)0 6. (4 + 3)-2 7. 
8. 
9. 
10. 
Simplify and express only with positive exponents:
11. 
12. 
By the end of this section you should be able to:
- Define integer exponents.
- Apply the Laws of Exponents for integer exponents.
Introduction
There are two lessons in this section as follows:
Lesson 01 Zero and Negative Exponents
In this lesson you will review the definition of zero and negative exponents i.e. you will review integer exponents. You will apply these definitions to rewrite simple expressions without exponents.
Lesson 02 Laws of Exponents
In this lesson you will review the Laws of Exponents and apply them to simplifying expressions which contain integer exponents.
Prerequisites
To be successful in this lesson, it would be helpful to know the following:
- Definition of natural number exponents.
- How to multiply and divide using natural exponents.
- The Laws of natural exponents.
