cin>>t;
for(int i=0;i<t;i++){

cin>>n>>k;
long long int s=0;
long long int e=n;
long long int mid =(s+e)/2;
long long int res=0;
// cout<<n<<k<<endl;
while(s<=e){
mid=(s+e)/2;
long long int cp=pow(mid,k);
if(cp==n){
res=mid;
break;
}
if(cp<n){
res=mid;
s=mid+1;
}
else{
e=mid-1;
}

        }
        cout<<res<<endl;

}

hey @yuvrajhcs, use pow function directly in if case instead storing it in another number.I have made changes to your code. You can check them here https://ide.codingblocks.com/s/105842
