To calculate the square root of a number using the SQRT function in Excel, follow these steps:
Open Excel and go to the spreadsheet where you want to perform the calculation.
In a cell, enter the number for which you want to calculate the square root.
In another cell, where you want the square root result to be displayed, use the SQRT function. The syntax for the SQRT function is: =SQRT(number)
For example, if you want to calculate the square root of the number 25, you would enter the formula in a cell like this: =SQRT(25)
Press Enter to get the square root result.
The result will be displayed in the cell where you entered the formula.
Note: Make sure that the number given as an argument in the SQRT function is a positive number; otherwise, Excel will return an error.
