A counter-example to Fermat's Last Theorem(?)

Question Q9.1.3

Fermat's Last Theorem states that no three positive integers $x$, $y$ and $z$ can satisfy the equation $x^n + y^n - z^n = 0$ for any integer $n>2$. Explain this apparent counter-example to the theorem:

In [x]: 844487.**5 + 1288439.**5 - 1318202.**5
Out[x]: 0.0
