After following these steps, you’ll see the square root of your number in the selected cell. Simple, right?

## 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

or `=25^(1/2)`

.

### Can I use cell references with the SQRT function?

Yes, you can. For instance, if the number is in cell A1, use `=SQRT(A1)`

.
