I just started learning some basic measure theory.(adsbygoogle = window.adsbygoogle || []).push({});

Could someone explain the difference between [tex] \overline{F(A \times A)} [/tex] and [tex] \overline{F(A) \times F(A)} [/tex] where A is a finite set. Also, how would this be different in A was an countably infinite set?

Thanks!
