  skos:definition """En mathématiques, un logarithme est la fonction réciproque d'une exponentiation, c'est-à-dire que le logarithme de base b d'un nombre réel strictement positif est la puissance à laquelle il faut élever la base b pour obtenir ce nombre. 
<br/>(Wikipedia, L'Encylopédie Libre, <a href="https://fr.wikipedia.org/wiki/Logarithme">https://fr.wikipedia.org/wiki/Logarithme</a>)"""@fr, """In mathematics, the <b>logarithm</b> is the inverse function to exponentiation. That means that the logarithm of a number <span class="texhtml mvar" style="font-style:italic;">x</span> to the <b>base</b> <span class="texhtml mvar" style="font-style:italic;">b</span> is the exponent to which <span class="texhtml mvar" style="font-style:italic;">b</span> must be raised to produce <span class="texhtml mvar" style="font-style:italic;">x</span>. For example, since <span class="texhtml">1000 = 10<sup>3</sup></span>, the <i>logarithm base</i> 10 of <span class="texhtml">1000</span> is <span class="texhtml">3</span>, or <span class="texhtml">log<sub>10</sub> (1000) = 3</span>. The logarithm of <span class="texhtml mvar" style="font-style:italic;">x</span> to <i>base</i> <span class="texhtml mvar" style="font-style:italic;">b</span> is denoted as <span class="texhtml">log<sub><i>b</i></sub> (<i>x</i>)</span>, or without parentheses, <span class="texhtml">log<sub><i>b</i></sub> <i>x</i></span>, or even without the explicit base, <span class="texhtml">log <i>x</i></span>, when no confusion is possible, or when the base does not matter such as in big O notation.
