2.  Exponents are a short hand way to write multiplication  Examples: 4 ·4 = 4 2 4·4·4 = 4 3 4·4·x·x·x= 4 2 x 3 = 16 x 3

3.  a m ·a n = a m+n  Examples:

4.  (a m ) n = a mn  Examples:

5.  (ab) m = a m b m  Examples:

6.  When negative numbers are raised to an exponent, the following rules hold true: If the exponent is odd- the answer is negative If the exponent is even- the answer is positive  Examples:
