Solución detallada

Sustituimos $u = 2^{x} \frac{\sin{\left(x \right)} \cos{\left(x \right)}}{e^{x}}$ .
Derivado $\log{\left(u \right)}$ es $\frac{1}{u}$ .
Luego se aplica una cadena de reglas. Multiplicamos por $\frac{d}{d x} 2^{x} \frac{\sin{\left(x \right)} \cos{\left(x \right)}}{e^{x}}$ :
1. Se aplica la regla de la derivada parcial:
  
  $\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$
  
  $f{\left(x \right)} = 2^{x} \sin{\left(x \right)} \cos{\left(x \right)}$ y $g{\left(x \right)} = e^{x}$ .
  
  Para calcular $\frac{d}{d x} f{\left(x \right)}$ :
  1. Se aplica la regla de la derivada de una multiplicación:
    
    $\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} h{\left(x \right)} = f{\left(x \right)} g{\left(x \right)} \frac{d}{d x} h{\left(x \right)} + f{\left(x \right)} h{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} h{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$
    
    $f{\left(x \right)} = 2^{x}$ ; calculamos $\frac{d}{d x} f{\left(x \right)}$ :
    1. $\frac{d}{d x} 2^{x} = 2^{x} \log{\left(2 \right)}$
    $g{\left(x \right)} = \cos{\left(x \right)}$ ; calculamos $\frac{d}{d x} g{\left(x \right)}$ :
    1. La derivada del coseno es igual a menos el seno:
      
      $\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}$
    $h{\left(x \right)} = \sin{\left(x \right)}$ ; calculamos $\frac{d}{d x} h{\left(x \right)}$ :
    1. La derivada del seno es igual al coseno:
      
      $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
    Como resultado de: $- 2^{x} \sin^{2}{\left(x \right)} + 2^{x} \log{\left(2 \right)} \sin{\left(x \right)} \cos{\left(x \right)} + 2^{x} \cos^{2}{\left(x \right)}$
  Para calcular $\frac{d}{d x} g{\left(x \right)}$ :
  1. Derivado $e^{x}$ es.
  Ahora aplicamos la regla de la derivada de una divesión:
  
  $\left(- 2^{x} e^{x} \sin{\left(x \right)} \cos{\left(x \right)} + \left(- 2^{x} \sin^{2}{\left(x \right)} + 2^{x} \log{\left(2 \right)} \sin{\left(x \right)} \cos{\left(x \right)} + 2^{x} \cos^{2}{\left(x \right)}\right) e^{x}\right) e^{- 2 x}$
Como resultado de la secuencia de reglas:

$\frac{2^{- x} \left(- 2^{x} e^{x} \sin{\left(x \right)} \cos{\left(x \right)} + \left(- 2^{x} \sin^{2}{\left(x \right)} + 2^{x} \log{\left(2 \right)} \sin{\left(x \right)} \cos{\left(x \right)} + 2^{x} \cos^{2}{\left(x \right)}\right) e^{x}\right) e^{- x}}{\sin{\left(x \right)} \cos{\left(x \right)}}$
Simplificamos:

$- 2 \tan{\left(x \right)} - 1 + \log{\left(2 \right)} + \frac{2}{\sin{\left(2 x \right)}}$

Respuesta:

$- 2 \tan{\left(x \right)} - 1 + \log{\left(2 \right)} + \frac{2}{\sin{\left(2 x \right)}}$
