1. What is Square Root?

The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3 because 3 × 3 = 9.

2. How Does the Calculator Work?

The calculator uses the mathematical square root function:

Where:

• \( x \) — The number you want to find the square root of (must be ≥ 0)
• \( y \) — The resulting square root value

3. Mathematical Explanation

Details: Square roots are fundamental in mathematics, used in geometry, algebra, and many real-world applications like calculating distances or areas.

4. Using the Calculator

Tips: Simply enter any non-negative number and click "Calculate" to find its square root. The result will be displayed with up to 4 decimal places.

5. Frequently Asked Questions (FAQ)

Q1: Can I calculate square roots of negative numbers?
A: Not with real numbers. Negative numbers have complex square roots (using imaginary unit i).

Q2: What's the square root of 0?
A: The square root of 0 is 0 (0 × 0 = 0).

Q3: How precise are the results?
A: Results are accurate to 4 decimal places.

Q4: What's the difference between √x and x^(1/2)?
A: They are mathematically equivalent - both represent the square root of x.

Q5: Can I calculate higher roots (cube roots, etc.) with this?
A: No, this calculator only calculates square roots. For other roots, you would need a different calculator.
