Ask the other soldier which is the right door and say tell me what he says, then the true soldier will tell you the wrong door that the false soldier told you, but the false soldier will tell you the right door that the true soldier told you wrong, the two doors are one, then you can escape through the other door.

Hi.
I would like to post this, though it has been posted already.
Just because you know who tells the truth does not mean that his door is the right one!!!!!!!!! Can you hear me? Magical truth man does not always stand in front of the right door! You only know who tells the truth. And youbwasted your question to know it. So great, you found out that the truth teller can do math and 2+2=4. Whoopdee-doo. That doesn’t mean that the truth tellers door is the right one. You’re missing the point. You’re not trying to figure out who lies and who tells the truth. You’re trying to find the exit. PLEASE stop posting just ask something obvious and go through the truth teller’s door. One question to one person. Then you go through one door. Correct answers explained above among a jillion wrong ones.

No, I won’t have to ask any question from any of the two guards. I’ll just await which door any or both of them will use when their guarding shift is over.

“at this exact moment, do I have hands?”

I do. If they say no then they are the liar and I will choose the other door, etc.

or I would ask them an obvious math question, like
“what does 2+2 equal?”

I would look at one guard’s shoes. If they were black ( or any other color ) I would ask if their shoes were black. If he says yes he is the truthful one. If he says no then he is the liar. I would then enter the truthful ones door.

Ask a question that you already know the true answer to: Is the Earth round? Does 1 + 1 = 2? Is my name (whatever your name is). The dishonest guard can only lie, so he will always give the incorrect answer to these type of questions. Et voila.

To ask the right (single) question you must focus on the answer, not who is lying or telling the truth. Once you get the answer you know which door leads to freedom and you go through it without knowing which guard is the liar. You don’t dare,

Ask either guard (or both at the same time) “Is the honest guard standing by the door to freedom?” Whoever says “yes” is standing by the freedom door. The other guard will say “no” or “I don’t know”, anything but “yes” so don’t go through that door.

Honest-Freedom door…Yes
Honest-Prison Door……No
Liar- Freedom door…Yes or something else, but not no
Liar- Prison Door…….No or something else, but not yes

Remember you don’t care who is lying when you phrase the single question this way. But if the liar obfuscates instead of giving a yes or no you can assume he is also the liar. If the liar says yes or no then you don’t know who the liar is but you don’t need to know.

If You ask A guard If the other one is alive, If he says no, You have the liar. Ask him which door is safe, When he tells you, Go through the opposite side.

If I can ask two questions at both Guards then there they are:

Question 1: Can the Guard who Speaks the Truth Lie it’s Truth?
-The Honest Guard will say no while the other will say yes.
Question 2: Which door is the Exit?
-By knowing which one lies and such then you already know who’ll point to the Exit.

the problem starts YOU ARE IN A ROOM WITH TWO DOORS And the prisoner knows from which door he was brought inside the room. He canchoose that door for exit. Why he should ask any guard.
