Can the the answer be true for every even $x$ and false for every odd $x$?

4 $exists xinmathbb N^*$ s.t. $y^xge0 forall xinmathbb R$
Translate. There is at one $x$ in $mathbb N^*$, s.t. whenever $y^x$ the number is always in $mathbb N$, and $y$ can be any number in $mathbb R$.

Ans: True. For $x=$ even number, $y^xge0$

  An answer can depend on the parity of $x$, for example the question "Is $x$ divisible by $2$?"

  You must have a typo in the first line, $x$ surely isn't quantified twice,
