Simplify each of the following expressions using the zero exponent rule for exponents. The zero exponent indicates that there are no factors of a number. To help understand the purpose of the zero exponent, we will also rewrite x5x-5 using the negative exponent rule. In the following example, when we apply the product rule for exponents, we end up with an exponent of zero. The expression 0 0 is indeterminate, or undefined. Zero Exponent Rule: a 0 = 1, a not equal to 0. For example,īut working with negative exponents is just rule of exponents that we need to be able to use when working with exponential expressions.Īpply the Negative Exponent Rule to both the numerator and the denominator.Īpply the Negative Exponent Rule to each term and then add fractions by finding common denominators. In other words, when there is a negative exponent, we need to create a fraction and put the exponential expression in the denominator and make the exponent positive. In this section, we will define the Negative Exponent Rule and the Zero Exponent Rule and look at a couple of examples. Negative exponents and zero exponents often show up when applying formulas or simplifying expressions.
