Poj 2109 power of cryptography Number Theory

Ask K to make n times of K equal to P.
Question: I am too lazy. However, you have to get familiar with high precision. If you have time, just make up the system. However, the valid range of types in C ++ must be noted as follows:

Type               Length    Valid number    Absolute Value Range

flo At 32 6 ~ 7 10 ^ (-37 )~ 10 ^ 38

Dou Ble 64 15 ~ 16 10 ^ (-307) ~ 10 ^ 308

Long double        128      18 ~ 19      10 ^ (-4931) ~10 ^ 4932

 
# Include <iostream> # include <cmath> using namespace STD; int main () {double N, P; while (CIN> N> P) cout <POW (P, 1/n) <Endl; return 0 ;}
