```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
    unsigned int a,b;
    cin>>a>>b;
    if(pow(a,b)>INT_MAX)
        cout<<(-1);
    else
        cout<<int(pow(a,b));
    return 0;
}
```
这样更简单



```cpp
#include<bits/stdc++.h>
using namespace std;

int main()
{
int a,b;
cin >> a;
cin >> b;
long long mul=1;
for (int i=1;i<=b;i++)
{
mul=mul*a;
if (mul>1000000000)
{
cout << "-1" << endl;
return 0;
}
}
cout << mul << endl;
return 0;
}

```
