WebJun 3, 2024 · The key idea is that different exponents can result in the same power, so the exponential function of complex numbers is not one-to-one, and its inverse function, the … WebThis is an interesting question. The real numbers are a subset of the complex numbers, so zero is by definition a complex number ( and a real number, of course; just as a fraction is a rational number and a real number). If we define a pure real number as a complex number whose imaginary component is 0i, then 0 is a pure real number.
