What is a Radical Fraction?

A radical fraction is a mathematical expression that combines a fraction with a radical (usually a square root).

Example:$$\frac{3\sqrt{8}}{4}$$438​​

In this example:

• 3 is the numerator coefficient
• 4 is the denominator
• √8 is the radical part

To simplify this expression manually, you would need to:

1. Simplify the radical √8
2. Multiply the coefficient
3. Reduce the fraction

The Radical Fraction Calculator performs all these steps automatically.
