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)

N,P = map(int,input().split())

from collections import Counter
def factorize(n):
    d = Counter()
    m = 2
    while m*m <= n:
        while n%m == 0:
            n //= m
            d[m] += 1
        m += 1
    if n > 1:
        d[n] += 1
    return d
fac = factorize(P)

ans = 1
for k,v in fac.items():
    x = v//N
    ans *= k**x

print(ans)
