Find the average of all multiples of 7 between 7 and 777, inclusive
Three pennies showing 2 heads and 1 tail lie on a table. Two of the coins are selected at random and turned over. What is the probability that now all three coins show the same side?

5. The Concept
The last time we were together we talked about simplify radicals
Today we’re going to review some concepts and then do some practice problems

6. The shift Radicals are easy for us if we accept one simple shift
This shift allows us to use our rules of exponents as opposed to using a second set of rules for radicals

7. Example Simplify the radical Let’s split that into our perfect squares
Convert back into “proper” radical form

8. Example
