Yes, the logical implication \( p \to q \) (read as "if \( p \), then \( q \)") is indeed logically equivalent to \( \neg p \lor q \) (read as "not \( p \) or \( q \)"). This is a well-known equivalence in propositional logic.

Here’s why:

- \( p \to q \) can be interpreted as saying that "if \( p \) is true, then \( q \) must also be true."
- This is equivalent to saying that either \( p \) is false (i.e., \( \neg p \) is true), or \( q \) is true.
  
Hence, \( p \to q \equiv \neg p \lor q \).

### Truth table for verification:

| \( p \) | \( q \) | \( p \to q \) | \( \neg p \lor q \) |
|:-------:|:-------:|:-------------:|:-------------------:|
|   T     |   T     |       T       |         T           |
|   T     |   F     |       F       |         F           |
|   F     |   T     |       T       |         T           |
|   F     |   F     |       T       |         T           |

Both expressions yield the same truth values, proving they are logically equivalent.
