Microsoft Calculator is a built-in Windows application that can perform basic mathematical operations, including finding square roots. This guide explains how to use it effectively for square root calculations.

How to Use Microsoft Calculator for Square Roots

Microsoft Calculator is a versatile tool that can help you find square roots with just a few clicks. Here's a step-by-step guide to using it:

  1. Open Microsoft Calculator: Press the Windows key + R to open the Run dialog box. Type "calc" and press Enter.
  2. Switch to Scientific Mode: By default, the calculator opens in Basic mode. Click the "View" menu and select "Scientific" to switch to the scientific calculator.
  3. Enter the Number: Type the number for which you want to find the square root. For example, type "25" if you want to find √25.
  4. Click the Square Root Button: Look for the "√x" button on the calculator. This button is typically located in the scientific functions section.
  5. View the Result: The calculator will display the square root of the number you entered. For √25, the result will be 5.

Tip

If you need to find the square root of a negative number, Microsoft Calculator will display an error message. Square roots of negative numbers are not real numbers but can be calculated using complex numbers.

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:

Square Root Formula

√x = y, where y × y = x

For example, the square root of 16 is 4 because 4 × 4 = 16. Microsoft Calculator uses this formula to compute square roots accurately.

Worked Examples

Let's look at a few examples of how to use Microsoft Calculator to find square roots:

Example 1: Finding √16

  1. Open Microsoft Calculator and switch to Scientific mode.
  2. Type "16" into the calculator.
  3. Click the "√x" button.
  4. The result will be "4".

Example 2: Finding √100
