Using the Laws of Exponents
Before you begin working with monomials and polynomials, you will
need to understand the laws of exponents. There are three laws or
properties that I am going to discuss in this lesson.
We will look at the following properties:
- Multiplying Powers with the Same Base
- Power of a Power Property
- Power of a Product Property
For each of the three laws, we will write a few examples in expanded
form. This will help you to understand why the law works. The I will
define the property. Finally we will look at a few examples.
Ok... let's get started!
Multiplying Powers with the Same Base
When a term does not contain an exponent, it is assumed to be 1.
3 = 31 y = y1 r = r1
Power of a Power Property
I know that these properties can be confusing. If you need direct video instruction, check out the Algebra Class E-course.
Power of a Product Property
Those are the only three properties that you'll need to remember for
this unit! As you complete the practice problems below, refer back to
the properties if needed!
Directions: For each problem identify the property used. Then simplify to lowest terms.
Great Job! Now let's move onto learning about monomials!
