#include <cmath>
using namespace std;

int main() {
double num = 13.13;
double result = sqrt(num);
cout << "Square root of " << num << " is " << result;
return 0;
}


	Square root of 13.13 is 3.62353



### c++ sqrt

	#include <iostream>
#include <cmath>
using namespace std;

int main() {
double x;
cout << "Enter a number : ";
cin >> x;

double result = sqrt(x);
cout << "sqrt(" << x << ") : " << result << endl;
}


	Enter a number : 5
sqrt(5) : 2.23607

Enter a number : 16
sqrt(16) : 4
