Bài 1:

#include <bits/stdc++.h>

using namespace std;

main()
{
    long long n;
    cin >> n;
    cout << n * n << " " << n * n * n << " " << n * n * n * n;
}

Bài 2:

#include <bits/stdc++.h>

using namespace std;

main()
{
    double f;
    cin >> f;
    cout << setprecision(2) << fixed << (f - 32) / 1.8;
}

`@`Bai 1:

#include <iostream>
#include <cmath>
using namespace std;
int main()
{
    long long n;
    cin>>n;  
    long long n2=n*n;
    long long n3=n2*n;
    long long n4 =n3*n;
    cout << n2 <<" "<<n3<<" "<<n4<<endl;
    return 0;
}

`@`Bai 2

#include <iostream>
#include <iomanip> 
using namespace std;
int main()
{
    double f;
    cin> f;
    double c=(f-32)/1.8;
    cout<<fixed<<setprecision(2)<<c<<endl;
    return 0;
}
