Grade 9 - zero and negative exponents.

Today we covered and verified that in fact all bases to the power of zero are always equal to 1.
Any base that has a negative exponent, you must take the reciprocal of that number. For example; x^-2 = 1/x^2
Overall, any x^-n = 1/x^n
Sorry about the notation, the blogger isn't as useful as a word processing document to do equations.
Out of textbook pg. 211-213 #1a-c, 2e-k, 4, 6ab, 7, 8, 10, 20, 28, 29.
Good luck and I will be checking your homework tomorrow afternoon.
