The root number n represents a person's zero-zero power, longn represents half the logarithm, and two numbers represent the same number.

In the range of real numbers, negative numbers and 0 have no logarithm, while in the range of complex numbers, negative numbers have logarithm. Because mathematics is established to serve real life, it must be a real mathematical model, and there is no mathematical model with negative real numbers in real life. Therefore, the case of negative real numbers in higher mathematics is only theoretically established.
