A square root of a number is a value that, when multiplied by itself, gives the number.
Example: 4 × 4 = 16, so a square root of 16 is 4.
Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16.
The symbol is √ which always means the positive square root.
Example: √36 = 6 (because 6 x 6 = 36)

In mathematics, a square root of a number a is a number y such that y2 = a, in other words, a number y whose square (the result of multiplying the number by itself, or y × y) is a. For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16.
The square root of a number is the value,that when it is multiplied by itself gives the number.
