Excel is a powerful and versatile tool that is widely used for various purposes like calculations, data analysis, and record keeping. One such useful function that Excel offers is calculating the square root of a number. In this article, we will discuss the step-by-step guide to calculate square root in Excel using different methods.
Method 1: Using the SQRT Function
The simplest way to find the square root of a number in Excel is by using the SQRT function. Follow these steps:
1. Open a new Excel workbook and enter the number you want to find the square root of in any cell (e.g., A1).
2. In another cell (e.g., B1), type the formula “=SQRT(reference)” without quotes, where ‘reference’ is the cell containing the number.
3. As an example, if you want to find the square root of 25 present in cell A1, then your formula will be “=SQRT(A1)”.
4. Press Enter and Excel will display the square root of the given number in the target cell (e.g., B1).
Method 2: Using Exponentiation
An alternative to using the SQRT function is utilizing exponentiation to calculate square root. Follow these steps:
1. Enter a number for which you want to find the square root in any cell (e.g., A1).
2. In another cell (e.g., B1), type “=POWER(reference,0.5)” without quotes, where ‘reference’ refers to the cell containing the number.
3. For instance, if you want to find the square root of 36 present in cell A1, then your formula will be “=POWER(A1, 0.5)”.
4. Press Enter and Excel will provide you with the calculated square root value.
Method 3: Calculating Square Root for Multiple Numbers
To calculate square root for multiple numbers at once, follow these steps:
1. In column A, enter the numbers you want to find the square roots for.
2. In the first cell of column B (e.g., B1), enter the formula “=SQRT(A1)” or “=POWER(A1, 0.5)”.
3. Click on the cell containing the formula (B1), and you will observe a small square dot at the bottom right corner of that cell. Drag this dot to cover all the cells in column B parallel to numbers in column A.
4. Excel automatically adjusts the formula references and calculates square roots for all corresponding numbers in column A.
Conclusion:
Calculating square roots in Excel is a straightforward operation, regardless of which method you choose. By following these steps, you can easily perform this task and utilize Excel to its fullest potential for various mathematical calculations.
