    A continuación,\(x\) y\(y\) son números reales arbitrarios que son estrictamente mayores que 0,\(p\) y\(q\) son constantes arbitrarias que son estrictamente mayores que uno.

    • \(q^{\log_q x}=x, \qquad \log_q \big(q^x\big)=x\)
    • \(\log_q x=\frac{\log_p x}{\log_p q}\)
    • \(\log_q 1=0, \qquad \log_q q=1\)
    • \(\log_q(xy)=\log_q x+\log_q y\)
    • \(\log_q\big(\frac{x}{y}\big)=\log_q x-\log_q y\)
    • \(\log_q\big(\frac{1}{y}\big)=-\log_q y\text{,}\)
    • \(\log_q(x^y)=y\log_q x\)
    • \(\lim\limits_{x\rightarrow\infty}\log_q x=\infty, \qquad \lim\limits_{x\rightarrow0}\log_q x=-\infty\)
    • La gráfica de\(\log_{10} x\) se da a continuación. La gráfica de\(\log_q x\text{,}\) para cualquiera\(q \gt 1\text{,}\) es similar.
