Solución detallada
Se da la desigualdad:
$$\left(4^{x} - \sqrt{3} \cos{\left(x \right)}\right) - 2 \sin{\left(x \right)} \cos{\left(x \right)} > 0$$
Para resolver esta desigualdad primero hay que resolver la ecuación correspondiente:
$$\left(4^{x} - \sqrt{3} \cos{\left(x \right)}\right) - 2 \sin{\left(x \right)} \cos{\left(x \right)} = 0$$

son puntos de cambio del signo de desigualdad en las soluciones.
Primero definámonos con el signo hasta el punto extremo izquierdo:
$$x_{0} < x_{34}$$
Consideremos, por ejemplo, el punto
$$x_{0} = x_{34} - \frac{1}{10}$$
=
$$-96.342174710087 + - \frac{1}{10}$$
=
$$-96.442174710087$$
lo sustituimos en la expresión
$$\left(4^{x} - \sqrt{3} \cos{\left(x \right)}\right) - 2 \sin{\left(x \right)} \cos{\left(x \right)} > 0$$
$$- 2 \sin{\left(-96.442174710087 \right)} \cos{\left(-96.442174710087 \right)} + \left(4^{-96.442174710087} - \sqrt{3} \cos{\left(-96.442174710087 \right)}\right) > 0$$
significa que una de las soluciones de nuestra ecuación será con:
$$x < -96.342174710087$$
Recibiremos otras soluciones de la desigualdad pasando al polo siguiente etc.

son puntos de cambio del signo de desigualdad en las soluciones.
Primero definámonos con el signo hasta el punto extremo izquierdo:
$$x_{0} < x_{34}$$
Consideremos, por ejemplo, el punto
$$x_{0} = x_{34} - \frac{1}{10}$$
=
$$-96.342174710087 + - \frac{1}{10}$$
=
$$-96.442174710087$$
lo sustituimos en la expresión
$$\left(4^{x} - \sqrt{3} \cos{\left(x \right)}\right) - 2 \sin{\left(x \right)} \cos{\left(x \right)} > 0$$
$$- 2 \sin{\left(-96.442174710087 \right)} \cos{\left(-96.442174710087 \right)} + \left(4^{-96.442174710087} - \sqrt{3} \cos{\left(-96.442174710087 \right)}\right) > 0$$
___
-0.948097219208122 + 0.583960357601758*\/ 3 > 0
significa que una de las soluciones de nuestra ecuación será con:
$$x < -96.342174710087$$
