SUMMARY
The discussion centers on proving the equation $(a)^\dfrac{1}{3}+(b)^\dfrac{1}{3}+(c)^\dfrac{1}{3}=0$ under the condition that $a+b+c-3(abc)^\dfrac{1}{3}=0$ and the inequalities $\neg((a)^\dfrac{1}{3}=(b)^\dfrac{1}{3})$, $\neg((b)^\dfrac{1}{3}=(c)^\dfrac{1}{3})$, and $\neg((c)^\dfrac{1}{3}=(a)^\dfrac{1}{3})$. By substituting $x=a^\dfrac{1}{3}$, $y=b^\dfrac{1}{3}$, and $z=c^\dfrac{1}{3}$, and applying the identity $(x^3+y^3+z^3-3xyz)=\dfrac{1}{2}(x+y+z)((x-y)^2+(y-z)^2+(z-x)^2)$, the proof is established that $x+y+z=0$ leads to the conclusion that $(a)^\dfrac{1}{3}+(b)^\dfrac{1}{3}+(c)^\dfrac{1}{3}=0$.
