Python| sympy.perfect_power() 方法

在sympy.perfect_power()方法的帮助下，我们可以找到两个整数b和e使得b ^e等于给定的数字n 。

Syntax:
perfect_power(n)

Parameter:
n – It denotes an integer.

Returns:
Returns a tuple of integers (b, e) such that b^e == n.

示例 #1：

# import perfect_power() method from sympy
from sympy import perfect_power
  
n = 64
  
# Use perfect_power() method 
b, e = perfect_power(n) 
      
print("n = {}".format(n))
print("b = {} and e = {}.".format(b, e))
print("{}^{} == {}".format(b, e, n)) 

输出：

n = 64
b = 2 and e = 6.
2^6 == 64

示例 #2：

# import perfect_power() method from sympy
from sympy import perfect_power
  
n = 64
  
# Use perfect_power() method 
b, e = perfect_power(n, big = False) 
      
print("n = {}".format(n))
print("b = {} and e = {}.".format(b, e))
print("{}^{} == {}".format(b, e, n)) 

输出：

n = 64
b = 8 and e = 2.
8^2 == 64
