a^x/log(x)

Solución detallada

Se aplica la regla de la derivada parcial:

$\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$

$f{\left(x \right)} = a^{x}$ y $g{\left(x \right)} = \log{\left(x \right)}$ .

Para calcular $\frac{d}{d x} f{\left(x \right)}$ :
1. $\frac{\partial}{\partial x} a^{x} = a^{x} \log{\left(a \right)}$
Para calcular $\frac{d}{d x} g{\left(x \right)}$ :
1. Derivado $\log{\left(x \right)}$ es $\frac{1}{x}$ .
Ahora aplicamos la regla de la derivada de una divesión:

$\frac{a^{x} \log{\left(a \right)} \log{\left(x \right)} - \frac{a^{x}}{x}}{\log{\left(x \right)}^{2}}$
Simplificamos:

$\frac{a^{x} \left(x \log{\left(a \right)} \log{\left(x \right)} - 1\right)}{x \log{\left(x \right)}^{2}}$

Respuesta:

$\frac{a^{x} \left(x \log{\left(a \right)} \log{\left(x \right)} - 1\right)}{x \log{\left(x \right)}^{2}}$
