I just wanted to ask how do you change a v (or sign) to an ^ (and sign) in propositional logic whilst proving logical equivalence? For instance this is the problem: Using a transformational proof, prove the following logical equivalence: (¬(¬(x v y) v ¬(x v z) <----> x v (y ^z)

Question
Hi,
I just wanted to ask how do you change a v (or sign) to an ^ (and sign) in propositional logic whilst proving logical equivalence?
For instance this is the problem:
Using a transformational proof, prove the following logical equivalence:
(¬(¬(x v y) v ¬(x v z) <----> x v (y ^z)
So I got this far:
(x v y) v (x v z) <----> Law of Negation
x v (y v z) <-----> Distributive Law
Now I cannot figure out how to change the V (or) to a ^ (And) using propositional logic laws. Any ideas would be greatly appreciated, have an exam tmr ;(
If you answer this,
Thank you so much you are a lifesaver.
