Solución detallada
  1. Se aplica la regla de la derivada parcial:

    ddxf(x)g(x)=f(x)ddxg(x)+g(x)ddxf(x)g2(x)\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(x)=xlog(5)f{\left(x \right)} = x \log{\left(5 \right)} y g(x)=xlog(x)g{\left(x \right)} = x \log{\left(x \right)}.

    Para calcular ddxf(x)\frac{d}{d x} f{\left(x \right)}:

    1. La derivada del producto de una constante por función es igual al producto de esta constante por la derivada de esta función.

      1. Según el principio, aplicamos: xx tenemos 11

      Entonces, como resultado: log(5)\log{\left(5 \right)}

    Para calcular ddxg(x)\frac{d}{d x} g{\left(x \right)}:

    1. Se aplica la regla de la derivada de una multiplicación:

      ddxf(x)g(x)=f(x)ddxg(x)+g(x)ddxf(x)\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}

      f(x)=xf{\left(x \right)} = x; calculamos ddxf(x)\frac{d}{d x} f{\left(x \right)}:

      1. Según el principio, aplicamos: xx tenemos 11

      g(x)=log(x)g{\left(x \right)} = \log{\left(x \right)}; calculamos ddxg(x)\frac{d}{d x} g{\left(x \right)}:

      1. Derivado log(x)\log{\left(x \right)} es 1x\frac{1}{x}.

      Como resultado de: log(x)+1\log{\left(x \right)} + 1

    Ahora aplicamos la regla de la derivada de una divesión:

    x(log(x)+1)log(5)+xlog(5)log(x)x2log(x)2\frac{- x \left(\log{\left(x \right)} + 1\right) \log{\left(5 \right)} + x \log{\left(5 \right)} \log{\left(x \right)}}{x^{2} \log{\left(x \right)}^{2}}

  2. Simplificamos:

    log(5)xlog(x)2- \frac{\log{\left(5 \right)}}{x \log{\left(x \right)}^{2}}


Respuesta:

log(5)xlog(x)2- \frac{\log{\left(5 \right)}}{x \log{\left(x \right)}^{2}}
