Quickly calculate square roots, cube roots, or any nth root using the free Root Calculator by Calculator Hub HQ — ideal for students, teachers, and professionals.
What Is a Root in Mathematics?
In mathematics, a root is a value that, when raised to a specific power, gives the original number. The most common types are:
- Square root (√) – a number that, when squared, gives the original number
- Cube root (∛) – a number that, when cubed, gives the original number
- Nth root – a general form where any number is raised to the power of n
For example:
- √25 = 5, because 5² = 25
- ∛27 = 3, because 3³ = 27

Frequently Asked Questions
What is the square root of a negative number?
The square root of a negative number is an imaginary number. For example, √(-9) = 3i.
Can I use decimals or fractions?
Yes! The calculator supports decimals (e.g., 16.81) and fractions (e.g., 81/16).
What is an nth root?
An nth root is the number that must be multiplied by itself n times to get the original number. For example, the 4th root of 81 is 3, because 3⁴ = 81.
Is this calculator accurate for large numbers?
Absolutely. The calculator can handle large integers and decimals without rounding errors in most cases.
