Reviewed by Calculator Editorial Team

The location of the square root button varies depending on the type of calculator you're using. Here's a guide to help you find it on different calculator models.

Basic Calculators

Basic calculators typically don't have a dedicated square root button. Instead, you'll need to use the exponent function to calculate square roots.

To calculate a square root on a basic calculator:

  1. Enter the number you want to find the square root of
  2. Press the exponent button (usually marked as "xy")
  3. Enter "0.5" as the exponent
  4. Press the equals button (=)

For example, to find the square root of 25:

25 x0.5 = 5

Scientific Calculators

Scientific calculators typically have a dedicated square root button, often marked with a radical symbol (√). This button is usually located in the upper row of function keys, near the exponent and logarithm functions.

To use the square root function on a scientific calculator:

  1. Press the square root button (√)
  2. Enter the number you want to find the square root of
  3. Press the equals button (=)

For example, to find the square root of 36:

√36 = 6

Graphing Calculators

Graphing calculators, like those used in advanced math classes, typically have a square root function that can be accessed through the math menu. The exact location may vary by model, but it's usually found in the math or function catalog.

To use the square root function on a graphing calculator:

  1. Navigate to the math menu
  2. Select the square root function (often labeled as "√")
  3. Enter the number you want to find the square root of
  4. Press the enter or equals button

For example, to find the square root of 49:

√49 = 7

Programmable Calculators

Programmable calculators, like the HP-48 series, may have the square root function available through the function catalog. The exact location depends on the specific model and software version.

To use the square root function on a programmable calculator:

  1. Access the function catalog
  2. Search for the square root function (often labeled as "√")
  3. Enter the number you want to find the square root of
  4. Execute the function

For example, to find the square root of 64:

√64 = 8

Calculator Apps

Most calculator apps for smartphones and computers have a dedicated square root button, often marked with a radical symbol (√). This button is typically found in the scientific or advanced mode of the app.

To use the square root function in a calculator app:

  1. Open the calculator app
  2. Switch to scientific or advanced mode if needed
  3. Press the square root button (√)
  4. Enter the number you want to find the square root of
  5. Press the equals button (=)

For example, to find the square root of 81:

√81 = 9
