Today we will compute positive integer powers of nonnegative integers. compute=to solve positive integer =whole numbers greater than zero nonnegative integers =positive numbers

Positive integer- a whole number greater than 0. Examples of positive integers: 15191,0081,500,609,433 Non examples of positive integers: ½

Examples of nonnegative integers are: ,0008,000,454,099 Non examples on nonnegative integers: ,009,857-1/2 Nonnegative integer- a whole number greater than 0.

Power or Exponent- a mathematical notation indicating the number of times a quantity is multiplied by itself. Examples of power or exponent: Non examples of power or exponents: ½¼

4 6 Base Exponent The exponent is sometimes referred to as the power.

- Name the following What’s this?

What is the meaning of 4 6 ? 4 6 means to multiply the base 4 by itself 6 times.

3 4 3x3x3x3 81 Multiply 3x3x3x3 =

It is important to know how to compute exponents because they are used when finding the area of certain places. It is on your grade level standards probably all the way until you graduate 12 th grade What other reasons can you think of why it is important to compute exponents?

Definition of Exponent An exponent tells how many times a number is multiplied by itself. 3 4 Base Exponent

What an Exponent Represents An exponent tells how many times a number is multiplied by itself. 3 4 = 3 x 3 x 3 x 3

How to multiply out an Exponent to find the Standard Form = 3 x 3 x 3 x

4 2 = 16 4 x 4 = Write the Power in Standard Form Make sure that you do not read this question as 4 x 2.

2 3 = 8 2 x 2 x 2 = 4 x 2 = 8 How did you do?

3 2 = 9 3 x 3 = 9 Write the Power in Standard Form Again, make sure that you do not read this question as 3 x 2.

You try these

Write as the product? 3 x 3 = 93 2

Write as the Product? 5 x 5 x 5 x 5 =

What is an exponent? Write in standard form? 5x5 An exponent tells how many times a number is multiplied by itself

The End Congratulations, now you know a little more about exponents.
