Answer 1

I searched Google under the key words "math power" and "math power negative" to get these possible sources:

http://www.homeschoolmath.net/teaching/zero-exponent-proof.php
http://www.math.com/school/subject2/lessons/S2U2L2DP.html
http://oakroadsystems.com/math/expolaws.htm

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
