2. Today we will understand how to identify, read, and write positive integer powers of nonnegative integers. Identify=to point out Positive integer=whole numbers greater than zero nonnegative numbers=positive numbers

3. Positive integer- a whole number greater than 0. 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. –A power or exponent is placed to the right of and above another number.

4. Understanding Exponents 3 4

5. 3 4 3x3x3x3 81 Multiply 3x3x3x3 = 81 3 1 3 3 3 4 3 2

6. It is important to know how to read and write 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 read and write exponents?

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

8. 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
