 # How to calculate the square root in Excel

Calculating the square root of numbers is common in mathematical equations. If you want to do that calculation in Microsoft Excel, you have a couple of ways to do it. We will show you how.

## What is a square root?

There square root of a number is the value you multiply by itself to get the original number. For example, the square root of 25 is 5. This is because if you multiply 5 by 5, you get 25.

## Calculate the square root in Excel with the caret symbol

One way to find the square root in Excel is to use the ^ (caret) symbol. Use this method if you don’t want to use a dedicated square root function (which is our second method below).

To get started, first open your spreadsheet with Microsoft Excel. In your spreadsheet, find the number for which you want to find the square root. In the spreadsheet, click the cell where you want to see the resulting square root. In the selected cell, type the following formula and press Enter. In this formula, substitute `D2`with the cell where you have your number.

Suggestion: the ^ (caret) symbol is located on the number 6 on the keyboard. Press Shift + 6 to type the symbol.

`=D2^(1/2)` To directly specify your number in the formula, substitute `D2`in the formula with your number. Like this:

`=225^(1/2)` And instantly, Excel will display the resulting square root in the selected cell. ## Calculate the square root in Excel with the SQRT function

If you want to use a function to calculate the square root, use the `SQRT`dedicated Excel function to find square roots. This function retrieves the same result as the previous method.

To use the function, first open your spreadsheet with Microsoft Excel. In the spreadsheet, select the cell where you want to view the answer. In the selected cell, enter the following `SQRT`function and press Enter. In this function, replace `D2`with the cell where your number is.

`=QUADRATO(D2)` If you want to use the number directly in the function, substitute it `D2`with your actual number. Like this:

`=QUADRATO(625)` Excel will calculate the square root and display it in the selected cell. And this is all.

## Bonus tip: insert square root symbol in Excel

By default, both of the above methods do not display the square root symbol (√). To add this symbol, you can use the `UNICHAR`Excel function in combination with your preferred square root search method.

If you use the caret symbol method to find the square root, please modify the formula as below to add the square root symbol before the answer:

`=UNICAR(8730)&D2^(1/2)`

If you use the `SQRT`function, modify it as follows to make it show the square root symbol at the beginning of the answer:

`=UNICAR(8730)&QUADRATO(D2)`

The selected cell now shows the symbol before the resulting square root number. And these are the ways to quickly get to the square root of a number. Very helpful!
