Problem Statement

There are N integers a_1, a_2, ..., a_N not less than 1.
The values of a_1, a_2, ..., a_N are not known, but it is known that a_1 \times a_2 \times ... \times a_N = P.

Find the maximum possible greatest common divisor of a_1, a_2, ..., a_N.

Constraints

1 \leq N \leq 10^{12}

1 \leq P \leq 10^{12}

Input

Input is given from Standard Input in the following format:

N P

Output

Print the answer.

Sample Input 1

3 24

Sample Output 1

2

The greatest common divisor would be 2 when, for example, a_1=2, a_2=6 and a_3=2.

Sample Input 2

5 1

Sample Output 2

1

As a_i are positive integers, the only possible case is a_1 = a_2 = a_3 = a_4 = a_5 = 1.

Sample Input 3

1 111

Sample Output 3

111

Sample Input 4

4 972439611840

Sample Output 4

206

Solution in Python (3.8.2) (judge verdict: Accepted)

from copy import deepcopy
from math import ceil
n, p = map(int, input().split())
ans = 1
q = deepcopy(p)
for i in range(2, int(p ** 0.5) + 2):
    cnt = 0
    while p % i == 0:
        p //= i
        cnt += 1
    if cnt > 0:
        ans *= i ** (cnt // n)

print(ans if p != q and n != 1 else q)
