How to evaluate exponents with fractional bases?
Exponents with fractional bases follow the same fundamental rules of exponents as those with integer bases. The exponent indicates how many times the fractional base is multiplied by itself. The key is to remember that the exponent applies to both the numerator and the denominator of the fraction.

The following diagram shows some examples of how to evaluate exponents with fractional bases. Scroll down the page for more examples and solutions of fractions raised to a power.

For a fractional base \(\frac{a}{b}\) raised to an exponent n:

\((\frac{a}{b})^n = \frac{a^n}{b^n}\)

This means you can raise the numerator to the power of n and the denominator to the power of n separately.

Example: Evaluate \((\frac{2}{3})^3\)

\((\frac{2}{3})^3 = \frac{2^3}{3^3} = \frac{8}{27}\)
