In this lesson on Rational Exponents 1, we learn about fractional exponents and how to define them. Through examples involving square roots and cube roots, we see how fractional exponents work and how they relate to radicals. We also learn how to simplify expressions with fractional exponents and real numbers. This is part one of a series on rational exponents, setting the foundation for future lessons on more complex problems involving fractional exponents.
Part 1 covers the meaning of a fractional exponent when the numerator is 1, and provides examples.
