Doubt on First Order Logic
Can anyone explain this how this implication is valid with an example ∃x (Px ⊕ Qx) <-- ∃xPx ⊕ ∃xQx

UGC NET CSE | January 2017 | Part 3 | Question: 60
The first order logic (FOL) statement $((R\vee Q)\wedge(P\vee \neg Q))$ is equivalent to which of the following? $((R\vee \neg Q)\wedge(P\vee \neg Q)\wedge (R\vee P))$ $((R\vee Q)\wedge(P\vee \neg Q)\wedge (R\vee P))$ $((R\vee Q)\wedge(P\vee \neg Q)\wedge(R\vee \neg P))$ $((R\vee Q)\wedge(P\vee \neg Q)\wedge (\neg R\vee P))$

GATE IT 2004 | Question: 3
Let $a(x, y), b(x, y,)$ and $c(x, y)$ be three statements with variables $x$ and $y$ chosen from some universe. Consider the following statement: $\qquad(\exists x)(\forall y)[(a(x, y) \wedge b(x, y)) \wedge \neg c(x, y)]$ ... $\neg (\forall x)(\exists y)[(a(x, y) \vee b(x, y)) \to c(x, y)]$
