    El número trascendental\(e\), aproximadamente\(2.71828\), se define como

    \[e=\lim_{n\to\infty}\left(1+\frac{1}{n}\right)^n.\nonumber \]

    La función exponencial\(\exp (x) = e^x\) y el logaritmo natural\(\ln x\) son funciones inversas satisfactorias

    \[e^{\ln x}=x,\quad\ln e^x=x.\nonumber \]

    Se aplican las reglas habituales de los exponentes:

    \[e^xe^y=e^{x+y},\quad e^x/e^y=e^{x-y},\quad (e^x)^p=e^{px}.\nonumber \]

    Las reglas correspondientes para la función logarítmica son

    \[\ln (xy)=\ln x+\ln y,\quad ln (x/y)=\ln x-\ln y,\quad \ln x^p=p\ln x.\nonumber \]
