Square root, In arithmetic, a

**square root**of a variety of a is various y such that y2 = a; in different phrases, quite a number y whose**square root**the result of multiplying the quantity by using itself, or y. y for example, four and −four are**square root**of 16 because 42 = (−4)2 = 16. Each nonnegative real number a has a completely unique nonnegative rectangular root, called the main square root, which is denoted through √a, in which √ is referred to as the novel signal or radix.
For example, the principal

**square root**of nine is three, which is denoted with the aid of √9 = 3, because 32 = 3 · 3 = 9 and three is nonnegative. The time period (or range) whose rectangular root is being considered is called the radicand. The radicand is the range or expression under the radical sign, in this situation 9.
Every superb wide variety a has rectangular roots: √a, that's tremendous, and −√a, that is poor. Together, those roots are denoted as ±√a (see ± shorthand). Even though the essential rectangular root of a high-quality quantity is most effective one among its two rectangular roots, the designation

**square root**is regularly used to consult the fundamental rectangular root. For wonderful a, the essential rectangular root also can be written in exponent notation, as a1/2.**Square roots**of poor numbers can be mentioned in the framework of complex numbers. More commonly, rectangular roots can be taken into consideration in any context wherein a perception of squaring of some mathematical objects is defined such as algebra of matrices, endomorphism rings, etc.

**Let's begin our code :**

#include<stdio.h>

#include<math.h>

int main()

{

int num; scanf("%d",#);

printf("Square root: %f",sqrt(num));

return 0;

}

Output: 25 Square root: 5
