Opener:Please complete the following on your *NEW* opener sheet!!! Please also leave your homework on your desk for me to check in.

The Geometric Mean between 3 and 6 is: 

x2= 18x = 3√2

Using the model above, find the Geometric Mean of each of the following pairs of numbers:

1.) 3 and 3

2.) 4 and 25

3.) 5 and 30

We used the idea of similar triangles to find the answers for # 5.  Today we're going to use Geometric Mean as a shortcut for this!!
