Tips for Calculating Square Root in Excel
- Use the caret (^) operator: You can also use
=number^(1/2)to find the square root. For example,=16^(1/2)gives 4. - Cell references: Instead of typing numbers, use cell references like
=SQRT(A1). - Negative numbers: Remember, the SQRT function only works with positive numbers.
- Formatting: Use the Format Cells option to set the number of decimal places for your result.
- Check for errors: If you see
#NUM!, it means you’ve entered a negative number or an invalid argument.
Frequently Asked Questions
How do I find the square root of a number in Excel?

Can I use cell references with the SQRT function?
Yes, you can. For instance, if the number is in cell A1, use =SQRT(A1).
What happens if I try to find the square root of a negative number?
Excel will return a #NUM! error because the SQRT function doesn’t handle negative numbers.
How can I display more decimal places for the square root result?
Right-click the cell, choose Format Cells, and then select the number of decimal places you want.
Is there an alternative to the SQRT function?
Yes, you can use the caret operator: =number^(1/2).
Summary
