Perfect Squares

A perfect square is a number that is the square of an integer. Examples include 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, etc. Our calculator automatically detects if your number is a perfect square.

Square Root Properties

  • √(a × b) = √a × √b
  • √(a / b) = √a / √b
  • √a² = |a|
  • (√a)² = a
  • √1 = 1
  • √0 = 0

Cube Roots

A cube root of a number is a value that, when multiplied by itself three times, gives the original number. For example, the cube root of 27 is 3, because 3 × 3 × 3 = 27. The cube root symbol is ∛.
