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
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
