 What are Exponent Laws?  What are 3 things you know about exponents?  Pair up- 60 seconds  Square up- 60 seconds  share

 At UVIC the population of Rabbits triples every month. During the month of April there are 3 rabbits. How many rabbits will there be in October?  Step 1. How many months? ◦ 7 including April ◦ 3x3x3x3x3x3x3= 2187  Step 2. Can we write the expression above as a power?

 Write the following product in exponential form: ◦ 2x2x2x3x3x3x3 =2 3 x3 4 =648 ◦ 2x2x5x5x2x5x5 =2 3 x5 5 = is the Base 7 is the exponent

 Why do we say … Four squared for 4 2 two cubed for 2 3 Area= 4x4= 4 2 Area= 4x4= 4 2 Volume =2x2x2 =2 3

 When the base is negative it creates an interesting pattern… lets see if you can find it (-2) 1 (-2) 6 (-2) 2 (-2) 7 (-2) 3 (-2) 8 (-2) 4 (-2) 9 (-2) 5 (-2) 10 Powers with negative bases will be “+ve” if the exponent if even and “-ve” if the exponent is odd.
