WebbThe definition of a rational exponent is explained below. Rational exponents are defined as exponents that can be expressed in the form p q, where q ≠ 0. The general notation of rational exponents is x m n. Here, x is called the base (any real number) and m n is a rational exponent. Rational exponents can also be written as x m n = x m n. WebbThe Power Rule for Exponents. Let’s simplify (52)4. In this case, the base is 52 and the exponent is 4, so you multiply 52 four times: (52)4 = 52 • 52 • 52 • 52 = 58 (using the Product Rule – add the exponents). (52)4 is a power of a power. It is the fourth power of 5 to the second power. And we saw above that the answer is 58. Webb29 Introduction to Exponents and Polynomials Jenna Lehmann. Evaluating Exponential Expressions. When working with exponents, it might be more helpful to think of them as multiple instances of multiplication. Some exponents are going to be more straight-forward, but be careful of the writing of some exponents. opteron 6300 motherboard
