WebNov 5, 2015 · Explanation: The Real valued function ex:R → (0,∞) is one to one, with inverse function ln(x):(0,∞) → R. We can extend the definition of ex to the Complex valued function ez:C → C\{0}, but this is a many to one function, so it has no inverse function, unless we do something to limit the domain of ez or the range of lnz. For example ... WebThe real logarithmic function log b (x) is defined only for x>0. We can't find a number x, so the base b raised to the power of x is equal to zero: b x = 0 , x does not exist.
