	<title>Logaritmos</title>
    
    <p>Logaritmos podem ser calculados usando a <link xref="function">função</link> log.</p>
    <example>
    <p>log 100</p>
    </example>
    <p>Para calcular um logaritmo em uma base diferente use o <link xref="superscript">número subscrito</link> depois da função.</p>
    <example>
    <p>log₂ 32</p>
    </example>
    <p>Para calcular logaritmos naturais, use a função ln.</p>
    <example>
    <p>ln 1,32</p>
    </example>
    <p>Números de Euler podem ser inseridos usando a <link xref="variable">variável</link> e.</p>
    <example>
    <p>e^1,32</p>
    </example>
