Hello, Could I please get help with this discrete maths question. I'VE ATTACHED A PICTURE OF THE LOGIC SHEET BELOW: YOU CAN ONLY USE PROOFS 1-17!!!!!! Q1. Prove the following: [X v (Y ^ Z) ≡ (X v Y) ^ (X v Z)] I've attempted the question myself and this is what I got, if someone could look through my question and see if it's correct, and if its incorrect could you please provide a walkthrough to how to do the problem in detail? that would be great. thank you. My Attempt: [X v (Y ^ Z) ≡ (X v Y) ^ (X v Z)] Proof we observe for X,Y,Z LHS X v (Y ^ Z) X v (Y v Z) --- Golden Rule (11) X v (Y v Z) --- V/V Rule (9) (X v Y) v (X v Z) --- Golden Rule (11) (X v Y) ^ (X v Z)

Hello,
Could I please get help with this discrete maths question. I'VE ATTACHED A PICTURE OF THE LOGIC SHEET BELOW: YOU CAN ONLY USE PROOFS 1-17!!!!!!
Q1. Prove the following:
[X v (Y ^ Z) ≡ (X v Y) ^ (X v Z)]
I've attempted the question myself and this is what I got, if someone could look through my question and see if it's correct, and if its incorrect could you please provide a walkthrough to how to do the problem in detail? that would be great. thank you.
My Attempt:
[X v (Y ^ Z) ≡ (X v Y) ^ (X v Z)]
Proof we observe for X,Y,Z
LHS
X v (Y ^ Z)
X v (Y v Z) --- Golden Rule (11)
X v (Y v Z) --- V/V Rule (9)
(X v Y) v (X v Z) --- Golden Rule (11)
(X v Y) ^ (X v Z)
