Where Is Square Root on Windows Calculator

Reviewed by Calculator Editorial Team

Windows Calculator is a versatile tool that can perform basic arithmetic, conversions, and even some advanced mathematical functions. One common question is where to find the square root function in Windows Calculator. This guide provides clear instructions for both Windows 10 and Windows 11.

How to Find Square Root in Windows Calculator

The square root function is available in Windows Calculator, but its location varies slightly between Windows 10 and Windows 11. Follow the steps below to access it.

The square root of a number x is a value that, when multiplied by itself, gives x. Mathematically, it's represented as √x.

To calculate square roots in Windows Calculator:

  1. Open the Calculator application from your Start menu
  2. Switch to the Scientific mode (if available)
  3. Enter the number you want to find the square root of
  4. Press the square root button (√)
  5. View the result

If you're using the basic calculator mode, you can still calculate square roots by:

  1. Entering the number
  2. Pressing the exponentiation button (^)
  3. Entering 0.5 (since √x = x^0.5)
  4. Pressing the equals button (=)

Windows 10 Steps

In Windows 10, the square root function is located in the Scientific view of the Calculator app.

Step-by-Step Instructions

  1. Click the Start button and type "Calculator" in the search box
  2. Click on the Calculator app to open it
  3. In the top menu bar, click on "View" and select "Scientific"
  4. Locate the square root button (√) on the keypad
  5. Enter your number
  6. Click the √ button
  7. The result will appear in the display

Note: If you don't see the Scientific view option, you may be using the basic Calculator mode. In this case, you can still calculate square roots using the exponentiation method described above.

Windows 11 Steps

Windows 11 has a slightly different interface for accessing the square root function.

Step-by-Step Instructions

  1. Open the Start menu and search for "Calculator"
  2. Click on the Calculator app to launch it
  3. In the top-right corner, click on the three-dot menu icon
  4. From the dropdown menu, select "Scientific calculator"
  5. Locate the square root button (√) on the keypad
  6. Enter your number
  7. Click the √ button
  8. The result will appear in the display

Tip: You can also use the keyboard shortcut Ctrl+2 to switch to Scientific mode in Windows 11.

Alternative Methods

If you prefer not to use the Calculator app, here are alternative ways to find square roots:

Using PowerShell

You can calculate square roots using PowerShell with the following command:

[math]::Sqrt(25)

Using Command Prompt

For a quick calculation, you can use the following command in Command Prompt:

set /a root=25^0.5

Using Online Calculators

Many websites offer free online square root calculators that you can use if you don't have access to Windows Calculator.

Common Questions

Is the square root function available in all Calculator modes?

No, the square root function is primarily available in the Scientific mode of Windows Calculator. In Basic mode, you can calculate square roots by raising the number to the power of 0.5.

Can I calculate cube roots in Windows Calculator?

Yes, you can calculate cube roots by raising the number to the power of 1/3. For example, to find the cube root of 27, enter 27^1/3.

What if I don't see the square root button?

If you don't see the square root button, make sure you're in Scientific mode. If you're using the basic Calculator, you can still calculate square roots using the exponentiation method.

Can I use Windows Calculator for more advanced math?

Yes, Windows Calculator can perform a variety of advanced mathematical functions including trigonometric calculations, logarithmic functions, and more when in Scientific mode.
