When it comes to solving mathematical problems, radicals often play a big role. From square roots in basic arithmetic to cube roots and higher-order radicals in advanced algebra, calculating them manually can sometimes be time-consuming. That’s why we built this Radicals Calculator—a simple yet powerful online tool designed to give you quick and accurate results for any root calculation.

What Are Radicals?
A radical is the opposite of an exponent. For example:
- The square root (√) is the inverse of squaring a number.
- The cube root (∛) is the inverse of cubing a number.
- More generally, the n-th root of a number is the value that, when raised to the power of
n, equals the original number.
Examples:
- √16 = 4 because 4² = 16
- ∛27 = 3 because 3³ = 27
- ⁴√81 = 3 because 3⁴ = 81
Radicals are used in geometry, algebra, calculus, engineering, and even in daily financial calculations. Instead of relying on manual work or complex calculators, our Radicals Calculator allows you to enter any number and root value, then instantly see the result.

Example 3 – Fourth Root
- Number: 625
- Root: 4
- Result: 5 (since 5⁴ = 625)
Example 4 – Decimal Output
- Number: 50
- Root: 2
- Result: 7.071068 (accurate up to six decimal places)
