如何逆取n次根

Question

假设我有这个 python 脚本：

a = 2 ** 10
b = a ** # Code to reverse the process done for a.
print(a) # Prints 1024
print(b) # Should print 2

我该怎么做？

Answer 1

您可能想要找到该值的 xth 根。为此，您将结果提高到幂的倒数。所以，你的问题的答案是：

a = 2 ** x
b = a ** (1/x) # Code to reverse the process done for a.
print(a) # Prints 1024
print(b) # Should print 2
