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. That last example showed an easier way to handle negative exponents:

What are negative exponents? Negative exponents are powers (also called indices) with a negative sign (minus sign) in front of them. Examples of negative exponents: x^{-2} 3^{-4} 2b^{-\frac{1}{2}}
The negative exponents describe how many times we have to divide the base number. Visit BYJU’S to learn the definition, rules, procedure for solving the negative exponents with examples.
Below are a few examples of computing negative exponents given different cases. Negative base. Computing a negative exponent with a negative base is very similar, and just requires us to remember the rule that a negative base raised to an even exponent results in an even number, while a negative base raised to an odd exponent results in an odd ...
Negative exponents can be rewritten in two ways. Firstly, start with 1 and divide it by 2 the same number of times as the exponent. Secondly, take the reciprocal of the base and raise it to the positive exponent. Created by Sal Khan.
21 lut 2022 · It is common to hear the instruction “no negative exponents in the final answer.” Let’s explore a couple of techniques that allow us to clear our answer of negative exponents. Example \(\PageIndex{10}\)
A negative exponent is defined as the multiplicative inverse of the base, raised to the power which is of the opposite sign of the given power. In simple words, we write the reciprocal of the number and then solve it like positive exponents. For example, (2/3) -2 can be written as (3/2) 2.
