1) ложное  и истина только прошу не удаляй это решение это правильно

 

Answer 2

This is a question about logic and the meaning of implication and equivalence. I will try to answer it in detail using the information from the web search results .

Implication (p => q) means that if p is true, then q must be true as well. Equivalence (p <=> q) means that p and q have the same truth value, either both true or both false.

If we know that implication p => q is true and equivalence p <=> q is false, then we can deduce the following:

- p must be false, because if p were true, then q would be true as well, and p <=> q would be true, which contradicts the given information. - q must be true, because if q were false, then p => q would be false, which contradicts the given information.

Therefore, the truth values of p and q are: p = false, q = true.

Now, we can use these values to evaluate the equivalence q <=> p and the implication q => p.

- q <=> p is false, because q and p have different truth values. - q => p is false, because q is true and p is false.

Hence, the correct answer is 4) Л,Л.
