Calculate square roots (√), cube roots (∛), and nth roots with precision using our free online calculator. Perfect for math students, engineers, and scientific calculations. Our tool handles both perfect and imperfect roots with decimal precision.
Enter a number and click "Square Root (√)" to calculate its square root. Example: √25 = 5
Enter a number and click "Cube Root (∛)" to calculate its cube root. Example: ∛27 = 3
Enter a number, click "Nth Root (ⁿ√)", and specify the root value when prompted. Example: ⁴√16 = 2
Use the number pad and operators for basic calculations before applying root functions.
Yes, but only odd roots (like cube roots) of negative numbers are real numbers. Even roots (like square roots) of negative numbers are complex numbers and will show as "Error" in this calculator.
Our calculator uses JavaScript's built-in Math functions which provide precision up to 15-17 decimal places.
Square root is a specific case of nth root where n=2. Nth root allows you to calculate any root (like cube root where n=3, fourth root where n=4, etc.).
Yes, the calculator handles both whole numbers and decimal numbers for all root calculations.
