Solución detallada
Tenemos la ecuación:
23(324105)n324105+1=0.001\sqrt{\frac{2}{3}} \frac{\left(\frac{\sqrt{32}}{4 \sqrt{105}}\right)^{n}}{- \frac{\sqrt{32}}{4 \sqrt{105}} + 1} = 0.001
o
23(324105)n324105+10.001=0\sqrt{\frac{2}{3}} \frac{\left(\frac{\sqrt{32}}{4 \sqrt{105}}\right)^{n}}{- \frac{\sqrt{32}}{4 \sqrt{105}} + 1} - 0.001 = 0
o
6(210105)n3(1210105)=0.001\frac{\sqrt{6} \left(\frac{\sqrt{210}}{105}\right)^{n}}{3 \left(1 - \frac{\sqrt{210}}{105}\right)} = 0.001
o
(210105)n=0.00056(1210105)\left(\frac{\sqrt{210}}{105}\right)^{n} = 0.0005 \sqrt{6} \left(1 - \frac{\sqrt{210}}{105}\right)
- es la ecuación exponencial más simple
Sustituimos
v=(210105)nv = \left(\frac{\sqrt{210}}{105}\right)^{n}
obtendremos
v0.00056(1210105)=0v - 0.0005 \sqrt{6} \left(1 - \frac{\sqrt{210}}{105}\right) = 0
o
v0.00056(1210105)=0v - 0.0005 \sqrt{6} \left(1 - \frac{\sqrt{210}}{105}\right) = 0
Abrimos los paréntesis en el miembro izquierdo de la ecuación
v - 0.0005*sqrt61/105+sqrt/105+210/105) = 0

Dividamos ambos miembros de la ecuación en (v - 0.0005*sqrt(6)*(1 - sqrt(210)/105))/v
v = 0 / ((v - 0.0005*sqrt(6)*(1 - sqrt(210)/105))/v)

Obtenemos la respuesta: v = 0.00105571402044589
hacemos cambio inverso
(210105)n=v\left(\frac{\sqrt{210}}{105}\right)^{n} = v
o
n=log(v)log(210105)n = \frac{\log{\left(v \right)}}{\log{\left(\frac{\sqrt{210}}{105} \right)}}
Entonces la respuesta definitiva es
n1=log(0.00056(1210105))log(210105)=log(0.00054.76190476190476106210)+log(6)2log(105)+log(210)2n_{1} = \frac{\log{\left(0.0005 \sqrt{6} \left(1 - \frac{\sqrt{210}}{105}\right) \right)}}{\log{\left(\frac{\sqrt{210}}{105} \right)}} = \frac{\log{\left(0.0005 - 4.76190476190476 \cdot 10^{-6} \sqrt{210} \right)} + \frac{\log{\left(6 \right)}}{2}}{- \log{\left(105 \right)} + \frac{\log{\left(210 \right)}}{2}}
n2=log(0.00105571402044589)log(210105)=6.85353794434649log(210)2+log(105)n_{2} = \frac{\log{\left(0.00105571402044589 \right)}}{\log{\left(\frac{\sqrt{210}}{105} \right)}} = \frac{6.85353794434649}{- \frac{\log{\left(210 \right)}}{2} + \log{\left(105 \right)}}
