Preguntas Frecuentes — Square Root Calculator
What is the square root of a number?
The square root of a number n is the value x such that x × x = n. For example, √25 = 5 because 5 × 5 = 25. Every positive number has two square roots (positive and negative), but the principal square root is always positive.
What is a perfect square?
A perfect square is a whole number whose square root is also a whole number. Examples: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100. The calculator identifies perfect squares and shows the exact root.
Can you take the square root of a negative number?
Not in real numbers — the square root of a negative number is an imaginary number (e.g., √-4 = 2i). The calculator will indicate this. Cube roots of negative numbers are real (e.g., ∛-8 = -2).
