`pow` 这玩意比较玄学，少用

为什么？

@[zhangyuanxiao](/user/597089) 因为返回值是小数。这样应该就过了：（强制转化一下）
```cpp
#include<math.h>
#include<iostream>
using namespace std;
int main(){
long long a,b;
cin>>a>>b;
long long ans=pow(a+1,b);
cout<<ans;
return 0;
}
```

@[zhangyuanxiao](/user/597089) 他是先转换为`double`再乘滴，精度掉飞了，快速幂他不香嘛
