Question 2: Write each of the following sets in tabular forms:
\((vi)\) \(\;\) \(\{x|x \in Q \wedge x^2=2\} \)
Solution:
Tabular Form:
\(\{\}\)\(\;\)Or\(\;\) \(\phi\)
Explanation:
\(\{x|x \in Q \wedge x^2=2\} \) means that, we are looking for rational number such that:
\(x^2=2\)
\(x=\sqrt{2}\)
but \(\sqrt{2}\notin Q\)
So, the set is empty.
