Unformatted text preview: x^a * x^b = x^(a+b) Example: x^3 * x^9 = x^(3+9) = x^12 A good rule to do in understanding the laws of exponents is to write How do the laws work with rational exponents? The laws of exponents work the same with rational exponents as the laws work with solving other rational expressions. A fractional exponent like 1/n means to take the nth root: Provide the class with a third expression to simplify that includes rational (fractional) exponents. Here is an example for the class to solve: x^1/3 * x^23/3 The solution: x^(1/3 + 23/3) = x^(24/3) = x^8...
