When both the base and the variable are exponents, the usual elementary function we know so far may not be enough to solve this kind of equation. Thanks to Johann Heinrich Lambert and Leonard Euler for giving this Lambert W relation. #math | Math Avenue : Learn Math By Examples

This is Why The Lambert W Function is a MUST-have Algebra Tool in Your Algebra Toolbox The Lambert W Function is a useful tool to solve equations in which the unknown quantity occurs both in the base and in the exponent. It can be used in enumeration trees, combinatorics, maxima of Planck, Bose-Einstein, and Fermi-Dirac distribution, in enzyme kinetic in biochemistry, and in machine learning algorithms.
