    Q : Give an example of a non-constant analytic function f(z) such that the equation f(z) = 0 doesn’t have any solutions.
    A: f(z)=e^z
    Q: Find the number of zeroes of z^2+e^z-2 in the disc |z|<2
    A: Is the question about z^2 + e^(z-2) ? As written, it is a very hard question.

    zeroes of z2+ez-2z^2+e^z-2 in the disc |z|<2
    A: Is the question about z^2 + e^(z-2) ? As written, it is a very hard question.

    Q: True or False: There exists an analytic (one-valued) function on the complex plane whose square is equal to e^z-1.
    A: False. If f(z)^2 = e^z - 1, then differentiating both sides we get 2 f(z) f ' (z) = e^z. In particular f(0)^2 = 0 and 2 f(0) f ' (0) = 1. These two equalities are incompatible.
