7th Grade Math / Lesson 2: Exponents

EXPONENTS
What will we be learning in this lesson?


  • This lesson will explain and demonstrate the use of exponents.

    Vocabulary words are found in this purple color throughout the lesson. Remember to put these in your notebook.


EXPONENTS


    Exponential form of a number looks like this: 43 which means 4*4*4

    The 4 is the base: the number that gets multiplied repeatedly.

    The 3 is the exponent or power: it tells how many times to multiply the base.

    Ex) Exponential Form               Factors*               Standard form

                 2 4                                2 * 2 * 2 * 2                 16
                 6 2                                     6 * 6                       36

    *factors: things that are multiplied together

Exponents that are Zero
 
If your exponent is zero, the standard form of the number is 1. Raising a number to the power of zero means that you do not have any factors to multiply together.
 
Ex)      Exponential form                                Standard form
 
                50                                                             1
 
                100                                                            1
 
Any nonzero number raised to the zero power is 1.
