Use logical deduction to show that the following propositions are unconditionally true These two questions: 1) $P \to ((Q \lor R) \to P)$ and 2) $(P \to (Q \to R)) \to ( P \land Q \to R)$ It'd be really helpful if you could answer these for. I managed to answer the ones that give me a predetermined value of True or False for P Q R, but I don't know how to answer these using logical deduction. Thank you if you try!

Here is a proof for the first one:

\begin{align} \cfrac{ \cfrac{ \cfrac{\\{ P, Q \lor R \\} \cap \\{ P \\} \
ot = \emptyset}{P, Q \lor R \vdash P} \text{Assm} } {P \vdash (Q \lor R) \rightarrow P}\rightarrow \text {Right}} {\vdash P \rightarrow ((Q \lor R) \rightarrow P)}\rightarrow \text {Right} \end{align}

The key is to start at the bottom, and work your way back. Keep asking: given that my goal is ...., what rule allows me to get ...?
