Line 21:

<math> f(x) = \sum_{k=1}^K c_k x_1^{a_{1k}} \cdots x_n^{a_{nk}} </math>

then <math>f(x) = \sum_{k=1}^K e^{a_k^T y + b_k}</math>, where <math>a_k = (a_{1k},\dots,a_{nk} )</math> and <math>b_k = \log{(c_k}) </math>. After the change of variables, a posynomial becomes a sum of exponentials of affine functions.
