How To Compute Square Root In Excel

Introduction

Calculating the square root of numbers in Excel is a fundamental skill that enhances data analysis and mathematical operations within spreadsheets. Excel provides a SQRT function to perform this calculation, but it requires learning specific syntax and formulas.

While Excel functions can be tedious and time-consuming to learn, we'll explore how Sourcetable's AI-powered platform lets you compute square roots and perform any spreadsheet analysis simply by asking its chatbot - try it yourself to instantly answer any spreadsheet question.

Calculating Square Root in Excel

Using the SQRT Function

To calculate the square root of a positive number in Excel, use the SQRT function. Enter =SQRT(number) into a cell, replacing "number" with the value or cell reference. For example, =SQRT(A1) will return the square root of the value in cell A1.

Using the POWER Function

The POWER function can also compute square roots. Type =POWER(number, 1/2) into a cell, substituting "number" with your specific value or cell reference. This formula raises the number to the power of 1/2, effectively calculating its square root.

Using the Carat Operator

The caret operator (^) is another method to find the square root. Input the number followed by ^ (1/2) to represent the square root. For example, typing =A1^(1/2) will calculate the square root of the value in cell A1.

Additional Functions for Accuracy

Combine the SQRT function with ABS, ROUND, ROUNDUP, or ROUNDDOWN functions to handle negative numbers and to control the precision of the square root result. For instance, use =ROUND(SQRT(ABS(A1)),2) to get the square root of the absolute value in A1, rounded to two decimal places.

Applications in Data Analysis

Excel's square root calculations are essential for financial analysis, data analysis, engineering, and estimating unknown quantities. Utilizing the SQRT and POWER functions enhances the speed and accuracy in these areas.
