Exponent Mistakes (9/11/14)

It led to some great discussions in the groups, especially involving raising a number to the 0 power and negative exponents. One student asked, “Is there even such a thing as a negative exponent?” We’ll go over them all tomorrow and they’ll find out that there sure is! If you’re curious, here is the worksheet I gave them (slightly modified from Andrew’s).
