Have you ever found yourself needing to calculate square roots, cube roots, or nth roots in Google Sheets? Well, you’re in luck! In this article, we’ll explore how to use the SQRT function and custom formulas to easily perform these calculations.
SQRT Function Syntax, Argument, and Example in Google Sheets
The SQRT function is a handy tool in Google Sheets that allows you to calculate square roots. To use it, simply follow this syntax: SQRT(value), where “value” represents the positive number for which you want to find the square root.
For example, if you want to find the square root of 36, you can use the formula =sqrt(36), which will return the value 6.
But what if you try to use the SQRT function with a negative number? In that case, you will encounter an #NUM! error. However, you can still obtain the square root of a negative number by combining the ABS and SQRT functions, like this: =sqrt(abs(-36)), which will also return 6.
Square Root (SQRT) Array Formula
If you have multiple numbers or a list of numbers and want to find their square roots simultaneously, you can use a single SQRT formula. Let’s say your numbers are in the range C1:C10. In cell D1, you can enter the following array formula: =ArrayFormula(sqrt(C1:C10)). This will return an array of square roots in the range D1:D10.
Just keep in mind that the square root of a blank cell or a value of 0 will be 0.
Custom Square Root Formulas (SQRT Function Alternatives) in Google Sheets
Although the SQRT function is already available in Google Sheets, there are alternative formulas you can use to achieve the same result. These formulas might come in handy when calculating nth roots, as Google Sheets doesn’t have a specific function for that purpose.
Here are some alternative formulas you can use to find the square root of a number, such as 36:
- =sqrt(36)
- =36^(1/2)
- =POW(36,1/2)
- =power(36,1/2)
How to Return Cube Root or Nth Root in Google Sheets
Now that we’ve covered square roots, let’s move on to cube roots and nth roots in Google Sheets.
Cube Root in Google Sheets
To calculate the cube root in Google Sheets, you can use the following formulas:
- =value^(1/3)
- =POW(value,1/3)
- =power(value,1/3)
Here, “value” represents the positive number for which you want to calculate the cube root.
For example, if you want to find the cube root of 216, you can use any of the above formulas, and the result will be 6.
Nth Root in Google Sheets
From the examples above, you might have noticed two things. Firstly, the SQRT function is only used for calculating the square root. Secondly, to find the cube root or nth root, we can use the caret (^) symbol, along with the POW() or POWER() functions.
To calculate the nth root, you can simply modify the cube root formulas by replacing the exponent 1/3 with 1/n, where “n” represents the desired root.
Let’s say you want to find the 5th root of 3125. The result should be 5 since 3125 = 5 5 5 5 5. You can use any of the following formulas to calculate it:
- =B2^(1/5)
- =POW(B2,1/5)
- =POWER(B2,1/5)
That’s all for now! We hope this article has shed some light on how to use the SQRT function, along with custom formulas, to calculate square roots, cube roots, and nth roots in Google Sheets.
