Negative rational (fraction) exponents are just like regular negative exponents. To get rid of a negative exponent, we put it on the other side of the fraction bar. Likewise, whenever we see a negative fraction exponent, move it (and the base number) to the other side of the fraction bar to make it positive, then solve as usual. Easy!

Rational Equations are equations with powers in them. For example, we could see something like x^5 = 243. To solve these types of equations, we need to think OPPOSITES:
x^2 is the opposite of radical 2.
x^3 is the opposite of radical 3.
x^4 is the opposite of radical 4.
x^5 is the opposite of radical 5.....and so on. Do the opposite to each side until you get x by itself.
