3. Laws of Exponents

4. Power of a Quotient (6) Words: If you have a quotient inside the parentheses, and a power on the parentheses, then the power goes on each coefficient and/or each variable inside (both the numerator and the denominator.) Symbols: For any real number x and y ≠ 0, and any integer m, Examples:

18. When working with exponents, you're dealing with multiplication. Since order doesn't matter for multiplication, you will often find that you and a friend (or you and the teacher) have worked out the same problem with completely different steps, but have gotten the same answer in the end. This is to be expected. As long as you do each step correctly, you should get the correct answers. Don't worry if your solution doesn't look anything like your friend's; as long as you both got the right answer, you probably both did it "the right way". http://www.purplemath.com/modules/simpexpo2.htm
