Square Root Calculator Input Parameters & Defaults

Number (Radicand x)72Non-negative number to find the root of.
Custom Root Degree (n)3Degree n for additional n-th root calculation.

Square Root Calculator Mathematical Formula

\sqrt{x} = a\sqrt{b} \text{ where } x = a^2 b, \quad \sqrt[n]{x} = x^{1/n}

Square Root Calculator Worked Example

Finding the square root and simplified radical form of x = 72, plus its 3rd root.

  1. Factor largest perfect square: 72 = 36 × 2 = 6² × 2 -> Exact Radical = 6√2.
  2. Decimal Square Root √72 = 8.48528137.
  3. Cube Root ∛72 = 4.16016765.

Expressing √72 as 6√2 preserves infinite mathematical precision in geometry and trigonometry formulas before final rounding.

Square Root Calculator Frequently Asked Questions

Q: What is a perfect square?

A perfect square is an integer that is the square of another integer (such as 1, 4, 9, 16, 25, 36, 49, 64, 81, 100), meaning its square root is a whole number with zero remainder.
