The program is an illustration of built-in functions
<h3>What are 
built-in functions?</h3>
They are named program statements that have a predefined purpose 
<h3>The actual program</h3>
The program written in C++, where comments are used where required is as follows:
#include <iostream>
#include <cmath>
#include <ios>
#include <iomanip>
using namespace std;
int main (){
double x;
double y;
double z;
cin>>x;
cin>>y;
//This calculates the given expression
z = pow(sqrt(y),x);
cout << fixed<<setprecision(2);
cout<<z<<endl;
return 0;
}
