When reducing fractions, divide both the numerator and the denominator by the same factor.
Do NOT divide by a term!!!!
For these fractions, the fraction is not totally reduced if the same variable is in both the numerator and the denominator.
In general, I would suggest that you:
· clear outside exponents first
· then remove parentheses
· then re-locate variables with negative exponents
· and finally reduce the fraction so that a variable is only in the numerator or denominator but not both.

The denominator of the exponent is the index of the radical!

= 2
Base
When working with rational exponents, if the denominator of the exponent (which is the index of the radical) is even both the radicand and the simplification must be positive. If the leading coefficient is negative, the answer could be negative.
