Solución detallada
  1. Sustituimos u=tan(x)u = \sqrt{\tan{\left(x \right)}}.

  2. ddu5u=5ulog(5)\frac{d}{d u} 5^{u} = 5^{u} \log{\left(5 \right)}

  3. Luego se aplica una cadena de reglas. Multiplicamos por ddxtan(x)\frac{d}{d x} \sqrt{\tan{\left(x \right)}}:

    1. Sustituimos u=tan(x)u = \tan{\left(x \right)}.

    2. Según el principio, aplicamos: u\sqrt{u} tenemos 12u\frac{1}{2 \sqrt{u}}

    3. Luego se aplica una cadena de reglas. Multiplicamos por ddxtan(x)\frac{d}{d x} \tan{\left(x \right)}:

      1. Reescribimos las funciones para diferenciar:

        tan(x)=sin(x)cos(x)\tan{\left(x \right)} = \frac{\sin{\left(x \right)}}{\cos{\left(x \right)}}

      2. 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)=sin(x)f{\left(x \right)} = \sin{\left(x \right)} y g(x)=cos(x)g{\left(x \right)} = \cos{\left(x \right)}.

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

        1. La derivada del seno es igual al coseno:

          ddxsin(x)=cos(x)\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}

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

        1. La derivada del coseno es igual a menos el seno:

          ddxcos(x)=sin(x)\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}

        Ahora aplicamos la regla de la derivada de una divesión:

        sin2(x)+cos2(x)cos2(x)\frac{\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}}{\cos^{2}{\left(x \right)}}

      Como resultado de la secuencia de reglas:

      sin2(x)+cos2(x)2cos2(x)tan(x)\frac{\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}}{2 \cos^{2}{\left(x \right)} \sqrt{\tan{\left(x \right)}}}

    Como resultado de la secuencia de reglas:

    5tan(x)(sin2(x)+cos2(x))log(5)2cos2(x)tan(x)\frac{5^{\sqrt{\tan{\left(x \right)}}} \left(\sin^{2}{\left(x \right)} + \cos^{2}{\left(x \right)}\right) \log{\left(5 \right)}}{2 \cos^{2}{\left(x \right)} \sqrt{\tan{\left(x \right)}}}

  4. Simplificamos:

    5tan(x)log(5)2cos2(x)tan(x)\frac{5^{\sqrt{\tan{\left(x \right)}}} \log{\left(5 \right)}}{2 \cos^{2}{\left(x \right)} \sqrt{\tan{\left(x \right)}}}


Respuesta:

5tan(x)log(5)2cos2(x)tan(x)\frac{5^{\sqrt{\tan{\left(x \right)}}} \log{\left(5 \right)}}{2 \cos^{2}{\left(x \right)} \sqrt{\tan{\left(x \right)}}}
