Square Root Calculator
A square root calculator determines the principal square root (√x) and arbitrary nth roots of any positive real number. By finding the number that multiplies by itself to produce the radicand, it verifies that √144 = 12 and calculates irrational roots to six decimal places.

How Does the Square Root Calculator Work?
- Enter the number x.
- Select square root (√), cube root (∛), or specify an nth root.
- The calculator computes the root value and indicates whether x is a perfect square.
What Is the Square Root Formula?
√x = r such that r² = x
The number r which multiplied by itself yields x.
