Here's the Solution to this Question

1.Let x - is a student and P(x) - student enrolls in a math class.

So 'Every student enrolls in a math class' is \forall x P(x).

2.Let x - is a student and P(x) - student is in a class, Q(x) - a student drops a math course

So 'There is a student in a class who drops a math course' is \exist x P(x)\land Q(x).

3.Let x - is a student and P(x) - student is in a class, Q(x) - a student  wears an ID.

So 'Every student in this class wears an ID.' is \forall x P(x) \mapsto Q(x).

4.Let x - is a student and P(x) - student is in this class, Q(x) - a student  requests for uniform pass.

So 'At least one student in this class requests for uniform pass' is \exist x P(x)\land Q(x) .

5.Let x - is a student and P(x) - student is in the campus, Q(x) - a student access the free wifi connection.

So 'Every student access the free wifi connection in the campus' is \forall x P(x) \mapsto Q(x).
