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. Therefore, it is a root of the equation , where is the number to which we have to find power half. So, a number raised to the power half is nothing but the side of the square when the area is the original number - and it is also a root of the above mentioned equation. So you get the idea - square root.
