Self doubt on First Order logic
To check whether this statement is always true $(\forall x (P(x)) \implies \forall x (Q(x))) \implies (\forall x(P(x) \implies Q(x)))$ Ans: Let $(\forall x (P(x)) \implies \forall x (Q(x)))$ ... A: T and B: F, hence the statement given in question cannot be valid or always true or tautology. Is my approach correct? Is this a correct solution?
