## What is the rule for negative exponents?

A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa. For example, when you see x^-3, it actually stands for 1/x^3.

## Can exponential functions have a negative base?

The base of the exponential functions must be positive. The values of f(x) are negative or positive as function has limited range. Note: If base is negative, exponential functions will be complex functions.

## What are the rules for negative exponents?

## How do you simplify negative exponents?

A base that has a negative exponent can be changed to a fraction. The base and the exponent become the denominator, but the exponent loses its negative sign in the process. You then cap it all off with a 1 in the numerator.
