How to calculate a square root in Excel?

  • The square root is the number that, when multiplied by itself, gives the result of the original number.
  • The calculation of square roots is essential in various disciplines, such as finance, construction and telecommunications.
  • Excel allows you to easily calculate square roots using the SQRT function or by means of powers.
  • Knowing different methods for calculating square roots improves efficiency in everyday mathematical tasks.

square root in excel

Imagine that you are working in Excel and you need to calculate the square root of a number. What do you do? Many people would use the Windows calculator or even a physical calculator to get the result, however, this is something we can do from the spreadsheet. Square roots have multiple applications in a variety of fields, from technology to finance and construction.. Therefore, today we are going to show you how to quickly find out what the square root of any number is in Excel.

This process is really simple, because as in all situations in this program, we only need to know the formula and its syntax.

What is a square root?

The square root is a mathematical operation that allows us to obtain the number that, when multiplied by itself, results in the given number.. For example, the square root of 25 is clearly 5, because when multiplied by itself it gives us 25. It is worth being clear about this concept before going into the matter of how to calculate it in Excel, in order to have context about the task what we are doing

What is the square root operation used for?

As we mentioned at the beginning, the calculation of the square root has applications in all areas that merit mathematical operations. ANDIn general, mathematics is involved in everything and therefore those who know how to carry out this operation have a great advantage in obtaining the result they need quickly..

For example, In finance there is a measure called Standard Deviation that allows knowing the variability of a data set. In this way, it is possible to know the risk involved in making an investment and to obtain the result in question, it is necessary to occupy a square root operation.

In construction, square root calculations are used to obtain areas, dimensions, volumes and other important data for the correct planning of the structures. Meanwhile, in telecommunications we find the square roots in everything that refers to the modulation and transmission of signals.

Steps to calculate a square root in Excel

To obtain the square root of a number in Excel we will use the RAIZ function. Its syntax is really simple and it can be in two ways:

ROOT(Number) or ROOT(Cell)

In this sense, it will be enough to double click on an empty cell, enter the equal sign and then the function, open parentheses and then click on the cell that contains the number whose square root we want to calculate.

Finally, press Enter and you will immediately have the result.

Another way to get the square root in Excel

Mathematics offer various ways to reach the same solution and in this sense, there is another way to obtain the same result of the previous process, without the ROOT function. In this case, we will use an operation where the power sign will help us to reach the square root of the number that we indicate.

For this method, double click on an empty cell and enter:

= (Number or Cell with the number to calculate)+^ (1/2)

When finished, press Enter and you will have the same result as occupying the ROOT function.

Second root calculation method

With these two ways that we present to you, you will have the possibility of working with square roots in the fastest and most effective way from Excel. Knowing these methods will give you the opportunity to take advantage of them to speed up the calculations that you must carry out in your daily tasks.

It should be noted that, with the second method, you will be able to calculate not only square roots, but also cube roots just by changing the number 2 that is before the last parenthesis.
