**What Is Square Root Formula In Excel (SQRT)?**

When we multiply the number with the same number, we get the square of the number. The

Square Root in Excelis a built-inused to calculate the number’sMATH & TRIG functionSquare Rootor the multiplied numeric value, which can be done by entering the function directly or entering from the “Formulas” tab.

For example, the **Square Root** of the number **25 **in cell A1is** 5**, as shown below in cell **B1**.

- If we multiply the number
**5**by**5**, as**5 * 5**, we will get a value of**25**. - We can also write the equation as
**5**^{2.}

### Key Takeaways

- The
**Square Root in Excel**helps users find the numeric value that was multiplied twice to get its squared value. - It is a brainer function. With manual calculation, we need some calculators to do the task. But in Excel, it is just a supply of the number to the formula SQRT.
- We can use many methods to find the
**SQRT**as we saw to enter directly in the worksheet as an equation, or insert the formula. We also have the**VBA method,**as we learnt in**FAQ 2**. - We can use some functions like
**ABS(), POWER(),**etc., too, to find the**SQRT**of a number.

### Negative Square Root In Excel

**Square Root** works for negative numbers as well.

Let us consider an example to see if the **Square Root** of 36 is either 6 or -6.

- If the number
**-6**is squared, we will get a positive number of**36**, i.e.,**-6 * -6 = +36.**

As per the mathematics rule, we will get a positive number if we multiply the negative sign with the negative sign.

- And, of course,
**6 * 6 = 36**as well.

### Syntax Of Square Root In Excel

The syntax of the **Square Root Formula** is,

The argument of the **Square Root Formula** is,

It is the only mandatory parameter of the*number*:**SQRT function**. It is the numeric value we are trying to find the**Square Root**value.

### How To Calculate Square Root (SQRT) In Excel?

In Excel, we can calculate the **Square Root** not only by using the **Square Root** but also in several other ways, namely:

**Manual Method:**To use this function, we need to type the keyword**=SQRT,**and press the “**tab**” button, which will pop up the**SQRT function**, and it takes a single argument.**Function Method:**We can insert the function from the “**Function Library**” of the “**Formulas**” tab.

**Examples**

In Excel, we can calculate the square root not only by using the square root but also in several other ways.

**Example #1**

We have a list of numbers shown below.

The steps to find the **Square Root Value **are,

**Copy these numbers to Excel.****Open the formula in the B2 cell.****In this case, select the required cell, i.e., A2.****Now, drag and drop the formula to the remaining cells.**

#### Example #2

In this article’s earlier section, we mentioned that the **Square Root** in the Excel formula could work only for positive numbers. If we supply the negative number, we will get **#NUM! error.**

But we can apply another formula with the SQRT function to get this done. Now, look at the below negative numbers.

We have applied the **SQRT Excel function**, and we got **#NUM! errors** due to negative numbers.

To solve this issue, first, we need to convert all the negative numbers into positive ones. So, we will use the ABS functionABS FunctionABS Excel function or Absolute function is used to calculate the absolute value of a given number. The negative numbers given as input are changed to positive numbers and if the argument provided to this function is positive, it remains unchanged.read more, which can return the absolute value of a negative number. We do not need to apply this formula separately. Instead, we can nest this formula inside the **SQRT function** itself.

Firstly, the ABS function will convert the negative number to a positive number. Then, the **SQRT Excel function** will work properly because of the positive number supplied by the **ABS function**.

#### Example #3

We have learned how to calculate the **Square Root number** in the Excel formula. But we can find the square of the number too.

Now, look at the numbers below.

If we multiply 6 with 6, we will get **36**. As a result, i.e., the **Square Root** of the number 36 is 6. But we do not have any special formula to calculate the square value. But still, we can do this, which is the power of Excel.

By using an exponential symbol, we can solve this problem.

**Important Things To Note**

- The SQRT function can accept only numbers. If you supply anything other than the numerical value, we will get
**#VALUE! error.** - The SQRT function accepts only positive numbers. If you supply negative numbers, it will return the result as
**#NUM! error.** - We use the key “
**ALT+251**” to insert the**Square Root**symbol.

### Frequently Asked Question

**1. Can we provide any number to find the Square Root in Excel?**

We must remember that the **Square Root** formula can return the result only for positive numbers. If we supply the negative number, we will get a** #NUM! Error**, as shown below.

**2. Where is the Square Root function in Excel?**

We can find the **Square Root function **as follows:

First, choose an empty cell – select the “**Formulas**” tab – go to the “**Function Library**” group – click the “**Math & Trig**” option drop-down – select the “**SQRT**” function, as shown below.

The “**Function Arguments**” window opens. Enter the arguments in the “**Number**” field, and click “**OK**”, as shown below.

**3. How to use VBA code to find the Square Root in Excel?**

We can use the **VBA editor** to find the Square Root in Excel using the following steps, namely:**•** First, open the worksheet with the dataset.**•** Next, press the shortcut keys “**Alt+F11**”, and the VBA editor window opens, as shown below.**•** Then, click the path **Insert **–** Module**, which opens the window, as shown below.**•** Enter the following **VBA Code**,

Sub sqrt_Example()

sqr_root = Sqr(** number**)

End Sub

**•**Finally, run the

**VBA Code**to execute the code and get the result.

**4. What is the symbol for SQRT, and how to insert it in a cell?**

● The mathematical symbol for **SQRT **is,

● We can insert the symbol in an Excel cell using the shortcut key “**Alt+251**”, i.e., hold the “**ALT**” key and type the numbers 251, one after the other, from the number keypad. Automatically, the **SQRT symbol** gets inserted in the cell.
