$$\left(49^{\sin{\left(x \right)}}\right)^{\cos{\left(x \right)}} = 7^{\left(\sqrt{3}\right)^{\sin{\left(x \right)}}}$$
Solución detallada
Tenemos la ecuación
$$\left(49^{\sin{\left(x \right)}}\right)^{\cos{\left(x \right)}} = 7^{\left(\sqrt{3}\right)^{\sin{\left(x \right)}}}$$
cambiamos
$$- 7^{3^{\frac{\sin{\left(x \right)}}{2}}} + \left(49^{\sin{\left(x \right)}}\right)^{\cos{\left(x \right)}} - 1 = 0$$
$$- 7^{\left(\sqrt{3}\right)^{\sin{\left(x \right)}}} + \left(49^{\sin{\left(x \right)}}\right)^{\cos{\left(x \right)}} - 1 = 0$$
Sustituimos
$$w = \cos{\left(x \right)}$$
$$- 7^{\left(\sqrt{3}\right)^{\sin{\left(x \right)}}} + \left(49^{\sin{\left(x \right)}}\right)^{w} - 1 = 0$$
o
$$- 7^{3^{\frac{\sin{\left(x \right)}}{2}}} + \left(49^{\sin{\left(x \right)}}\right)^{w} - 1 = 0$$
Sustituimos
$$v = \left(49^{\sin{\left(x \right)}}\right)^{w}$$
obtendremos
$$- 7^{3^{\frac{\sin{\left(x \right)}}{2}}} + v - 1 = 0$$
o
$$- 7^{3^{\frac{\sin{\left(x \right)}}{2}}} + v - 1 = 0$$
hacemos cambio inverso
$$\left(49^{\sin{\left(x \right)}}\right)^{w} = v$$
o
$$w = \frac{\log{\left(v \right)}}{\log{\left(49^{\sin{\left(x \right)}} \right)}}$$
Entonces la respuesta definitiva es
hacemos cambio inverso
$$\cos{\left(x \right)} = w$$
Tenemos la ecuación
$$\cos{\left(x \right)} = w$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x = \pi n + \operatorname{acos}{\left(w \right)}$$
$$x = \pi n + \operatorname{acos}{\left(w \right)} - \pi$$
O
$$x = \pi n + \operatorname{acos}{\left(w \right)}$$
$$x = \pi n + \operatorname{acos}{\left(w \right)} - \pi$$
, donde n es cualquier número entero
sustituimos w:
