What is the Rule for Negative Exponents? There are two main rules that are helpful when dealing with negative exponents: a-n = 1/a n; 1/a-n = a n; How to Solve Fractions with Negative Exponents? Fractions with negative exponents can be solved by taking the reciprocal of the fraction.
A negative exponent means how many times to divide by the number. Example: 8-1 = 1 ÷ 8 = 1/8 = 0.125. Or many divides: Example: 5-3 = 1 ÷ 5 ÷ 5 ÷ 5 = 0.008. But that can be done an easier way: 5-3 could also be calculated like: 1 ÷ (5 × 5 × 5) = 1/53 = 1/125 = 0.008.
18 Ιουλ 2022 · In section 5.5, the exponent of the number in the denominator may be greater than the exponent of the number in the numerator. Definition: The Negative Exponent Rule. For any non zero real number a and any integer n, the negative exponent rule is the following. a−n = 1 an or 1 a−n = an a − n = 1 a n o r 1 a − n = a n.
The law of negative exponents states that, when a number is raised to a negative exponent, we divide 1 by the base raised to a positive exponent. The general formula of this rule is: a -m = 1/a m and (a/b) -n = (b/a) n .
The negative exponent rule states that a number with a negative exponent should be put in the denominator. For example, x^{-2}=\cfrac{x^{-2}}{1}=\cfrac{1}{x^{2}}
