# About This Calculator

The Fourth Root of a number is a value that, when multiplied by itself four times, gives the original number. It is equivalent to taking the square root of the square root (√√x).

This is useful in physics and chemistry, especially when dealing with the Stefan-Boltzmann law (T⁴) or certain volume/area scaling relationships.

How To Use

  1. Enter a **Positive Number** into the input field.
  2. The **Fourth Root** is displayed instantly.
  3. For negative numbers, the result is complex (imaginary), which is not handled by this real-number solver.
