Square Root Button on Mac Calculator

How to Use the Square Root Button

Using the square root function on your Mac calculator is straightforward. Here's a step-by-step guide:

1. Open the Calculator app on your Mac. You can find it in the Applications folder or by searching for "Calculator" using Spotlight.
2. Select the "Basic" view if it's not already selected. This view provides all the essential calculator functions.
3. Enter the number for which you want to find the square root. For example, type "25" if you want to find the square root of 25.
4. Click the square root button (√) on the calculator. This button is typically located in the top row of the calculator.
5. The calculator will display the square root of the number you entered. For 25, the result will be 5.

If you need to find the square root of a more complex number, you can use the same steps. The calculator will handle the computation for you.

Square Root Formula

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

For example, the square root of 16 is 4 because 4 × 4 = 16. The square root function is the inverse of squaring a number.

Worked Examples

Let's look at a few examples to illustrate how the square root function works:

Example 1: Square Root of 36

To find the square root of 36:

1. Enter "36" on the calculator.
2. Click the √ button.
3. The result will be 6, because 6 × 6 = 36.

Example 2: Square Root of 81

To find the square root of 81:

1. Enter "81" on the calculator.
2. Click the √ button.
3. The result will be 9, because 9 × 9 = 81.

These examples demonstrate how the square root function can be used to find the root of a number.
