(x^x + x - 7)/(x^x + 1)
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)=x+xx7f{\left(x \right)} = x + x^{x} - 7 y g(x)=xx+1g{\left(x \right)} = x^{x} + 1.

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

    1. diferenciamos x+xx7x + x^{x} - 7 miembro por miembro:

      1. La derivada de una constante 7-7 es igual a cero.

      2. Según el principio, aplicamos: xx tenemos 11

      3. No logro encontrar los pasos en la búsqueda de esta derivada.

        Perola derivada

        xx(log(x)+1)x^{x} \left(\log{\left(x \right)} + 1\right)

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

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

    1. diferenciamos xx+1x^{x} + 1 miembro por miembro:

      1. La derivada de una constante 11 es igual a cero.

      2. No logro encontrar los pasos en la búsqueda de esta derivada.

        Perola derivada

        xx(log(x)+1)x^{x} \left(\log{\left(x \right)} + 1\right)

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

    Ahora aplicamos la regla de la derivada de una divesión:

    xx(log(x)+1)(x+xx7)+(xx+1)(xx(log(x)+1)+1)(xx+1)2\frac{- x^{x} \left(\log{\left(x \right)} + 1\right) \left(x + x^{x} - 7\right) + \left(x^{x} + 1\right) \left(x^{x} \left(\log{\left(x \right)} + 1\right) + 1\right)}{\left(x^{x} + 1\right)^{2}}


Respuesta:

xx(log(x)+1)(x+xx7)+(xx+1)(xx(log(x)+1)+1)(xx+1)2\frac{- x^{x} \left(\log{\left(x \right)} + 1\right) \left(x + x^{x} - 7\right) + \left(x^{x} + 1\right) \left(x^{x} \left(\log{\left(x \right)} + 1\right) + 1\right)}{\left(x^{x} + 1\right)^{2}}
