I need help understanding more on how to apply the laws of logic appropriately for a and b. I would like an elaboration of the problem instead of only the solution please.

Part 2. Determine whether each argument is valid. If the argument is valid, give
a proof using the laws of logic. If the argument is invalid, give values for the pred-
icates P and Q over the domain a, b that demonstrate the argument is invalid.
(a)
3x (P(x) ^ Q(x))
... Jx Q(x) ^ Jx P(x)
(b)
Væ (P(x) V Q(x))
.. Vx Q(x) V Vx P(x)
