Answer 1

You posting the language you want it in would also be helpful :)
Since I see that you only have C++ as a course I'll just assume you want it in C++

#include <iostream>
#include <cmath> // For sqrt

int main()
{
std::cout << sqrt(5);
}

Answer 2

In Python and all languages where you have an exponentiation operator, it's sufficient to go like:

print(x**.5) # meaning x to the power of ½

Answer 3

Math.sqrt() in JS
