Square Root on Microsoft Calculator

Reviewed by Calculator Editorial Team

Microsoft Calculator is a versatile tool that can perform basic arithmetic operations, including square roots. This guide explains how to calculate square roots using the Windows Calculator app, including step-by-step instructions, formulas, and practical examples.

How to Calculate Square Roots on Microsoft Calculator

Calculating square roots on Microsoft Calculator is straightforward. Here's how to do it:

  1. Open the Calculator app on your Windows device.
  2. Switch to the Standard view if it's not already selected.
  3. Enter the number you want to find the square root of.
  4. Click the "√" (square root) button.
  5. The calculator will display the square root of your number.

Note: The square root function is available in the Standard view of the Calculator app. If you're using the Scientific or Programmer view, you may need to switch back to Standard to access this function.

Square Root Formula

The square root of a number x is a value that, when multiplied by itself, gives x. Mathematically, this is represented as:

√x = y where y × y = x

For example, the square root of 25 is 5 because 5 × 5 = 25.

Square roots can be calculated for both perfect squares (numbers that are squares of integers) and non-perfect squares. The calculator will provide an approximate value for non-perfect squares.

Worked Examples

Example 1: Square Root of a Perfect Square

Let's find the square root of 36:

  1. Open Calculator and switch to Standard view.
  2. Enter "36".
  3. Click the "√" button.
  4. The result will be "6" because 6 × 6 = 36.

Example 2: Square Root of a Non-Perfect Square

Let's find the square root of 2:

  1. Open Calculator and switch to Standard view.
  2. Enter "2".
  3. Click the "√" button.
  4. The result will be approximately "1.414213562" because 1.414213562 × 1.414213562 ≈ 2.
