\log\left(\prod_{k=1}^\infty Ax^k+k!\right) = A(\exp(x)-1)  \end{equation}  Then define a token $A$ such that $A^k=0$, $k>2$. \begin{equation}  \log\left(\prod_{k=1}^\infty Ax^k+f(k)\right) = A\sum_{k=1}^\infty \frac{x^k}{f(k)} + -A^2\sum_{k=1}^\infty \frac{x^{2k}}{2f(k)^2} -\frac{A^2}{2}\sum_{k=1}^\infty \frac{x^{2k}}{f(k)^2}  \end{equation}
