Enter the base and numerator, and denominator of the fraction exponent into the calculator. The calculator will determine the value of the fractional exponent.

## Fraction Exponent Formula

The following equation is used to calculate the value of a number raised to a fractional exponent.

B = x ^ d/^e
• Where B is the value of the equation
• x is the base number to be raised
• d is the numerator of the exponent
• e is the denominator of the exponent.

## Fraction Exponent Definition

A fraction exponent is an exponent that is displayed and calculated using a fractional of some whole number.

## How to calculate fraction exponent?

How to calculate a fractional exponent

1. First determine the base in number

This would be x in the formula above.

2. Next, determine the numerator and denominator of the epxonent

This will be d and e of the fractional exponent.

3. Finally, calculate the value of B

Calculate the total value of the number x raised to the fractional exponent of d/e.

## FAQ

What is the practical use of calculating fractional exponents?

Fractional exponents are used in various scientific, engineering, and financial calculations. They can help in determining growth rates, decay rates, and in the analysis of curves and other geometric shapes in calculus.

Can all numbers be raised to a fractional exponent?

Yes, any positive real number can be raised to a fractional exponent. However, the process and outcome might differ when dealing with negative bases, especially if the denominator of the exponent is even, which could lead to complex numbers.

How does a fractional exponent compare to a square root?

A fractional exponent with a denominator of 2 (e.g., (x^{1/2})) is equivalent to taking the square root of (x). Generally, a fractional exponent with a denominator (n) (e.g., (x^{1/n})) is equivalent to taking the (n)th root of (x).

Is it possible to have a negative fractional exponent?

Yes, a negative fractional exponent indicates two operations: taking the reciprocal of the base and then raising it to the positive fractional exponent. For example, (x^{-a/b}) is equivalent to (1/(x^{a/b})).
