English: So, e in this case is nothing but$\frac{h^{2}}{8m_{e}}\left\lbrack \frac{{n_{1}^{2}}^{}}{a^{2}} + \frac{{n_{2}^{2}}^{}}{b^{2}} + \frac{{n_{3}^{2}}^{}}{C^{2}} \right\rbrack$.
Telugu: కాబట్టి, ఈ సందర్భంలో e అనేది$\frac{h^{2}}{8m_{e}}\లెఫ్ట్\lbrack\frac{{n_{1}^{2}}^{a^{2}} + \frac{{n_{2}^{2}}{b^{2}} + \frac{{n_{3}^{2}}{C^{2}} \కుడి\rbrack$.
