Calculate square roots with step-by-step solutions, perfect square identification, and visual representations
A square root of a number is a value that, when multiplied by itself, gives the original number. The square root symbol (√) is called a radical.
If √a = b, then b² = a
Perfect squares are numbers whose square roots are whole numbers. Examples include 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
