Root Calculator – Calculate Square & Cube Roots Online
Our online Root Calculator allows you to quickly calculate square roots and cube roots with step-by-step explanations. Perfect for students, teachers, engineers, and anyone working with numbers who wants accurate results instantly.
What is a Root Calculator?
A square root is a number that, when multiplied by itself, equals a given value.
For example, the square root of 25 is 5 because 5 × 5 = 25.
In math, the square root symbol is √, and it helps us find a number’s base value. Square roots are used in geometry, physics, engineering, and many everyday calculations — from finding the length of a diagonal to analyzing data in statistics.
- Square Root (√): Finds the number that, when squared, equals the input.
- Cube Root (∛): Finds the number that, when cubed, equals the input.
Using an online root calculator saves time, reduces errors, and provides a clear breakdown of the calculation, making it ideal for math homework, engineering formulas, and financial calculations.
