Here are the new rules along with an example or two of how to apply each rule: The Definition of: , this says that if the exponent is a fraction, then the problem can be rewritten using radicals. Here, the final answer should have only positive exponents; also notice that to evaluate a number raised to a negative exponent, the exponent must first be made positive. 3. Typically it is easier to simplify when we use rational exponents, but this exercise is intended to help you understand how the numerator and denominator of the exponent are the exponent of a radicand and index of a radical. According to CAPS, the rational exponent law is introduced in Grade 11 but you may choose to introduce learners to the rational exponent law \(a^{\frac{m}{n}}=\sqrt[n]{a^{m}}\) at this stage.
