What are squares and square roots?
The square root is just the opposite process of squaring a number. Suppose, if we square a number n, such as n^2, then the square root of n^2 is equal to the original number n.
square root - Square root of a number is a value, which on multiplied by itself gives the original number. Suppose, x is the square root of y, then it is represented as x=√y or we can express the same equation as x2 = y. Here,’√’is the radical symbol used to represent the root of numbers. The positive number, when multiplied by itself, represents the square of the number. The square root of the square of a positive number gives the original number.
For example, the square of 3 is 9, 32 = 9 and the square root of 9, √9 = 3. Since 9 is a perfect square, hence it is easy to find the square root of such numbers, but for an imperfect square like 3, 7, 5, etc., it is really tricky to find the root.
