Thanks, I'll take a look at it, although I find myself doubtful.

Welcome to PF, joo!

In university they still use the graphical approach. ;)

In addition they use approximation algorithms, like the method of Newton-Raphson (which is based on a Taylor series expansion).

It's only the really bold ones in math that use the Lambert W function, which is a function that has only been invented to be able to write the solution to your equation.

As far as I know, no one really uses it.

The first solution for your equation is ##x=-{W(-\frac 1 {14} \ln(2)) \over \ln(2)} \approx 0.07525##.

But Lambert used it and they made a movie on his life among sheep:

Oh! So the W comes from Walt Disney! :D
