The Root Calculator is a simple and easy-to-use online tool for calculating the square root, cube root, and other nth roots of a number. Enter a number, select the required root, and click Calculate Root to get the result instantly.

What is a Root?

A root is a value that, when multiplied by itself a specific number of times, gives the original number.

For example:

  • Square root: √64 = 8 because 8 × 8 = 64
  • Cube root: ∛27 = 3 because 3 × 3 × 3 = 27
  • Fourth root: ⁴√16 = 2 because 2⁴ = 16

The general formula for an nth root is:

ⁿ√x = x^(1/n)

How to Use the Root Calculator

Using this calculator is very simple:

  1. Enter the number for which you want to calculate the root.
  2. Select the required root, such as Square Root, Cube Root, or Nth Root.
  3. If you select Nth Root, enter the value of n.
  4. Click the Calculate Root button.
  5. The calculated result will be displayed immediately.

Examples

Square Root

For the number 144:

√144 = 12

Cube Root

For the number 125:

∛125 = 5

Fourth Root

For the number 81:

⁴√81 = 3

Nth Root

For example, the 5th root of 32 is:

⁵√32 = 2

because:

2⁵ = 32

Where is Root Calculation Used?

Root calculations are commonly used in mathematics, algebra, geometry, physics, engineering, statistics, and computer science. They are especially useful when solving equations, calculating distances, analyzing mathematical functions, and working with powers and exponents.

Important Note

An even root of a negative number does not have a real-number result. For example, √−16 is not a real number. However, odd roots of negative numbers can have real results, such as:

∛−27 = −3
