Basic Syntax for Finding the Nth Root in Excel
Discovering the nth root of a number in Excel requires understanding basic syntax. This section will explain two solutions: Using a Built-in Function and Using a Formula. Both options will help you quickly and easily find the nth root of a number.
Using Built-in Function
The Nth Root function is an inbuilt feature in Excel that enables the user to find the number which, when multiplied by itself N times, equals a specific value. This built-in function is an efficient way to simplify complex mathematical calculations.
Here’s a 4-step guide on how to use this feature:
- In your Excel worksheet, select the cell where you want to display the result of the Nth root calculation.
- Type “=NthRoot(number, root)” into the formula bar and hit enter (without quotes).
- Replace ‘number‘ with the actual number you want to find the Nth root of.
- Replace ‘root‘ with the value of N for which you want to find the root.
This built-in function works best with non-negative numbers. In case of negative numbers, Excel returns an error message; hence it is essential to use this function wisely.
Interestingly, finding roots through computer technology goes all way back to Babylonians around 4000 years ago. They used clay tablets containing tables listing squares (x^2), cubic powers (x^3), and fourth powers (x^4) as their basis for finding roots.

Using a Formula
To compute the Nth root of a number in Excel, you can follow a formula. Here’s a 6-Step guide to help you find the Nth root of any number in Excel:
- Choose a cell where you want your result to display
- Type = followed by the number you want to take the nth root of, then ^ for “to the power of” and type 1/n (where n is equal to the nth root you’re trying to find)
- Close with ) and hit Enter
- Your answer will appear in your chosen cell
- Note: If you don’t have access to superscript formatting, replace 1/n with ^(1/n).
- You can also use Excel’s built-in function named POWER. The syntax for POWER is POWER(number,power), but instead of hard-coding the exponent or power into this function, we divide it by n.
Additionally, formulas can be altered based on user requirements such as finding an nth-root based on consecutive inputs from users.
To minimize errors while using this formula, it’s best practice to double-check your calculations or use multiple formulas as an additional layer of verification. Another suggestion is using named ranges instead of cell references when working with formulas; this makes it easier to read and edit formulas without breaking them.

Tips for Accurate Results
Be precise with your answer when finding the nth root of a number in Excel. Rounding and precision can change it significantly. Input format is important too. Let’s investigate these solutions further.
Rounding and Precision
When it comes to finding the Nth root of a number in Excel, rounding and precision play a significant role. Precision refers to the exactness of your calculation’s results, while rounding can alter those results to some degree. It is crucial to be mindful of both factors for accuracy.
To ensure precise results, use the ROUND function with enough decimal places for adequate precision. Additionally, you may consider using the ROUNDUP or ROUNDDOWN functions based on your specific needs. However, keep in mind that these functions will round up or down to the nearest number rather than giving a precise decimal value.
Furthermore, when working with significant numbers or calculations that require extensive precision, consider using Excel’s Precision As Displayed feature. This will allow you to maintain control over displayed decimals despite Excel’s default rounding rules.
By paying attention to rounding and precision throughout your Nth root calculations, you can achieve accurate results in Microsoft Excel every time.
Excel may not judge you for improper input format, but your calculations will show just how clueless you are.
Proper Input Format
When it comes to accurately finding the nth root of a number in Excel, ensuring proper input format is crucial for getting the desired output. With the right input format, you can avoid errors and save time.
Here’s a simple 3-step guide to follow for the proper input format:
- Start by selecting an empty cell where you want to display the nth root result.
- Enter
=number^(1/nth power)
into the cell, replacing “number” with the actual value and “nth power” with the desired root value. - Press Enter on your keyboard to see the calculated result.
It’s important to note that any error in formatting (such as using commas instead of periods or incorrect syntax) will lead to inaccurate results. Be sure to proofread before entering your formula.
Apart from following proper input format, it’s also important to ensure that you have chosen the correct method for calculating roots. The two most common methods are using either a fractional exponent or Excel’s built-in ROOT function.
In my experience, I once overlooked a minor syntax error while entering my formula which led to hours of troubleshooting and frustration before realizing my mistake. Always pay attention to even the smallest details when working with formulas in Excel.
