In this lesson, we learn about rational exponents and how they relate to radicals. We learn that a rational exponent has a meaning in terms of roots and powers, and that the numerator of the rational exponent refers to a power, while the denominator refers to the root. We also learn that perfect squares and perfect cubes are rational numbers, while other radicals are irrational. The lesson concludes with the importance of simplification and rationalizing denominators.
