Solución detallada
Tenemos la ecuación:
$$\sqrt{4 x + 7} \left(\left(- \left(\frac{3}{2}\right)^{x_{62}} + \left(\left(\frac{2}{3}\right)^{5} x^{2} - 29\right)\right) - 5\right) = 0$$
Ya que la parte derecha de la ecuación es igual a cero, la solución de la ecuación será, si por lo menos uno de los factores en la parte izquierda de la ecuación es igual a cero.
Obtenemos ecuaciones
$$4 x + 7 = 0$$
$$- \left(\frac{3}{2}\right)^{x_{62}} + \frac{32 x^{2}}{243} - 34 = 0$$
resolvemos las ecuaciones obtenidas:
1.
$$4 x + 7 = 0$$
Transportamos los términos libres (sin x)
del miembro izquierdo al derecho, obtenemos:
$$4 x = -7$$
Dividamos ambos miembros de la ecuación en 4
x = -7 / (4)

Obtenemos la respuesta: x1 = -7/4
2.
$$- \left(\frac{3}{2}\right)^{x_{62}} + \frac{32 x^{2}}{243} - 34 = 0$$
Es la ecuación de la forma
a*x^2 + b*x + c = 0

La ecuación cuadrática puede ser resuelta
con la ayuda del discriminante.
Las raíces de la ecuación cuadrática:
$$x_{2} = \frac{\sqrt{D} - b}{2 a}$$
$$x_{3} = \frac{- \sqrt{D} - b}{2 a}$$
donde D = b^2 - 4*a*c es el discriminante.
Como
$$a = \frac{32}{243}$$
$$b = 0$$
$$c = - \left(\frac{3}{2}\right)^{x_{62}} - 34$$
, entonces
D = b^2 - 4 * a * c = 

(0)^2 - 4 * (32/243) * (-34 - (3/2)^x62) = 4352/243 + 128*(3/2)^x62/243

La ecuación tiene dos raíces.
x2 = (-b + sqrt(D)) / (2*a)

x3 = (-b - sqrt(D)) / (2*a)

o
$$x_{2} = \frac{243 \sqrt{\frac{128 \left(\frac{3}{2}\right)^{x_{62}}}{243} + \frac{4352}{243}}}{64}$$
$$x_{3} = - \frac{243 \sqrt{\frac{128 \left(\frac{3}{2}\right)^{x_{62}}}{243} + \frac{4352}{243}}}{64}$$
Entonces la respuesta definitiva es:
$$x_{1} = - \frac{7}{4}$$
$$x_{2} = \frac{243 \sqrt{\frac{128 \left(\frac{3}{2}\right)^{x_{62}}}{243} + \frac{4352}{243}}}{64}$$
$$x_{3} = - \frac{243 \sqrt{\frac{128 \left(\frac{3}{2}\right)^{x_{62}}}{243} + \frac{4352}{243}}}{64}$$
