Radical Simplify Calculator

Mathematics often requires breaking down square roots into their simplest radical form, but doing it manually can be time-consuming and error-prone. That’s why we created the Radical Simplify Calculator — a free, easy-to-use online tool that instantly reduces square roots into their most simplified radical expression.

What is a Radical Simplify Calculator?

A Radical Simplify Calculator is a digital tool designed to simplify square roots into their simplest radical form. Instead of leaving a number under the square root sign, the tool factors the number into perfect squares and non-perfect squares, then extracts the largest perfect square outside the radical.

For example: 50=25×2=52\sqrt{50} = \sqrt{25 \times 2} = 5\sqrt{2}50​=25×2​=52​

The calculator does this instantly — no manual calculations required.

How to Use the Radical Simplify Calculator

Using this calculator is straightforward. Here’s a step-by-step guide:

  1. Enter the number:
    In the input box labeled “Enter Number (inside √)”, type the number you want to simplify.
  2. Click Calculate:
    Press the Calculate button. The tool will process the input and display the simplified radical.
  3. View result:
    The result appears in the “Simplified Radical” box. For example, entering 72 will give you 6√2.
  4. Reset if needed:
    Use the Reset button to clear the input and start over with a new number.

Example Calculations

Here are a few examples to better understand how the calculator works:

  • Example 1:
    Input: 18
    Simplification: 18=9×2=32\sqrt{18} = \sqrt{9 \times 2} = 3\sqrt{2}18​=9×2​=32​ Output: 3√2
  • Example 2:
    Input: 72
    Simplification: 72=36×2=62\sqrt{72} = \sqrt{36 \times 2} = 6\sqrt{2}72​=36×2​=62​ Output: 6√2
  • Example 3:
    Input: 144
    Simplification: 144=12\sqrt{144} = 12144​=12 Output: 12
  • Example 4:
    Input: 98
    Simplification: 98=49×2=72\sqrt{98} = \sqrt{49 \times 2} = 7\sqrt{2}98​=49×2​=72​ Output: 7√2
