expressing a boolean function in another way

Question

The following boolean expression is given:

g(p,q,r) = ((p->q') -> r)

Depict this boolean function only by using the operations ∧ (AND), v (OR), ¬ (NEGATION).

How can I do this?

I thought I could replace just the q' with ¬q, so:

g(p,q,r) = ((p -> ¬q) -> r)

But i have no idea, how to replace the implication symbols.

Answer 1

((p∧¬q)∧¬r)

or

(p AND NOT q) AND NOT r
