Rational exponents are exponents that are fractions, so they are also called fractional exponents. Using the definition, you'll learn how to transform nth roots into rational exponents. The properties for powers of integer exponents are also valid for rational exponents. For example, we add exponents when two numbers with same base are multiplied. So the exponents can be both integers or fractions. Other properties are valid as well, like zero, and negative power. In a simplified form, all exponents must be positive and exponents in the denominator must be integers. The examples involve problems where you need to write a radical expression with rational exponents, etc.
