Square Root Calculator and nth Root Finder

What is a Square Root Calculator?

A square root calculator finds the value that squares to your number.

This square root calculator also works for cube roots and any nth root.

It handles whole numbers and decimals with ease.

Odd roots of negative numbers work as well.

The tool shows clear results with familiar math symbols.

How It Works

Type a number.

Pick the root type.

Choose Square Root or Cube Root or Custom.

Enter a custom root value when you pick Custom.

Press Calculate or press Enter.

You see the decimal answer with up to six places.

For square roots you see a simplified radical when possible.

Example, the square root of 8 equals 2√2 and about 2.828.

Inputs

• Number: Enter a whole number or a decimal.
• Root Type: Pick Square Root or Cube Root or Custom nth Root.
• Custom Root: Enter a root value of 1 or greater.

Outputs

• Result: Shows the symbol and the decimal value.
• Rounding: Results round to six decimal places.
• Simplified Radical: For square roots of positive numbers it shows the radical form.
• Keyboard: Press Enter to calculate fast.

Notes and limits

• Even roots of negative numbers return an error message.
• Custom root must be at least 1.
• The tool simplifies only square roots.
• Large inputs round at six decimals.
