Last Extra Credit for the year

Here is an opportunity for you to maximize your extra credit.  You may do two of the three problems for extra credit.  The work will need to have a post date of no later than April 27 to receive the extra credit.  Be very specific in your explanations of how you solved the problem and what proof you have that you are correct.  


Be sure to do your post in Word and copy and paste into the blog.  In addition, don't forget to start the post with your first and last initial and the period you have math.


Extra Credit:  You may select and submit up to two of these problems for extra credit.
