The power law relationship of Zipf's law can be expressed in an equivalent logarithmic form, which is useful for visualizing the distribution on a log-log plot. This form is written as $\log n_i = -\alpha \log i + c$, where $n_i$ is the frequency of the $i^{ extrm{th}}$ most frequent word, $\alpha$ is the distribution's exponent, and $c$ is a constant. On a log-log plot, the frequencies of words, excluding a few highly frequent exceptions, roughly form a straight line.
