Answer 1

What do you want to know with this?

Answer 2

Take a look at RPN (reverse polish notation) and Shunting Yard algorithm. They should help you solve this.

Answer 3

#include <iostream>
using namespace std;

int main() {
long double x;
long double y;
long double result;
cin >> x;
cin >> y;
result = (x+y^2)/27+x^y;
cout << result;
return 0;
}
