The image contains a mathematical statement invoking De Morgan's Law for sets. It states the following:

Given a collection of sets $F_a$ indexed by $a \in I$, the complement of the intersection of these sets is equal to the union of the complements of the individual sets:

$F^c = \left( \bigcap_{a \in I} F_a \right)^c = \bigcup_{a \in I} F_a^c$

This is a direct application of De Morgan's Laws for sets:

1. The complement of an intersection of sets is the union of the complements: $\left( \bigcap_{a \in I} F_a \right)^c = \bigcup_{a \in I} F_a^c$

2. Similarly, the complement of a union of sets is the intersection of the complements: $\left( \bigcup_{a \in I} F_a \right)^c = \bigcap_{a \in I} F_a^c$

These laws are fundamental in set theory and are widely used in proofs and logical manipulations.
