a. X+2y+6/5
b. 2ab/x+y-5x+7
c. X-y+3xy/2+x/4y
d. 2ab/x la puterea a 2

Answer 1

#include <iostream>
using namespace std;

int main()
{
float x,y,a,b;
cin>>x>>y>>a>>b;
cout<<x+2.0*y+6.0/5.0<<endl;
cout<<((2.0*a*b)/x)+y-(5.0*x)+7.0<<endl;
cout<<x-y+(3.0*x*y)/2.0+x/(4.0*y)<<endl;
cout<<((2.0*a*b)/x)*((2.0*a*b)/x);
return 0;
}

Se pune .0 ca sa afiseze numerele cu virgula
