The equation you provided,

$x^3 + y^3 = z^3$

is a classic example of a Diophantine equation, which seeks integer solutions for $x$, $y$, and $z$. According to Fermat's Last Theorem, no three positive integers $x$, $y$, and $z$ can satisfy this equation for $n > 2$. Therefore, for $n = 3$, as in your case, there are no positive integer solutions that satisfy this equation.

Reasoning:

1. Fermat's Last Theorem states that $x^n + y^n = z^n$ has no non-zero integer solutions for $x$, $y$, and $z$ when $n$ is an integer greater than 2.
2. In this case, since $n = 3$, the theorem applies, and we conclude that there are no non-trivial solutions (non-zero integer values for $x$, $y$, and $z$).
