Real World Examples
Standard Root
∜625 = 5 (since 5×5×5×5 = 625).
Decimal Root
∜10 ≈ 1.778.
# 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
- Enter a **Positive Number** into the input field.
- The **Fourth Root** is displayed instantly.
- For negative numbers, the result is complex (imaginary), which is not handled by this real-number solver.
