Describe two laws of exponents and provide an example illustrating each law. Explain how to simplify your expression. How do the laws work with rational exponents? Provide the class with a third expression to simplify that includes rational (fractional) exponents

    x^a * x^b = x^(a+b)

    (x^a)^b = x^ab

    x^(a/b) = the bth root of x^a, so

    [x^(a/b)]^b = x^a

    The laws work with all rational exponents
