What´s the solution of this equation?:
X = 2 ln(X).
Thanks. Ludovicus


No real solutions.
Complex solutions -2 W(-1/2), where W is the
Lambert W function. Get many
solutions by taking all the branches of W.

Using the principal branch of log, we get approximately
x = 1.588047265 + 1.540223501 i and
x = 1.588047265 - 1.540223501 i
