Question

Choose the main technique to prove the following statement. √ 3 √ 3 \sqrt{3}  is irrational.

Answer

T4: two-step proof to show  p ↔ q ≡ T p ↔ q ≡ T p \leftrightarrow q \equiv T

Answer

T3: indirect proof by contradiction to show  p ≡ T p ≡ T p \equiv T

Answer

T1: direct proof to show  p → q ≡ T p → q ≡ T p 	o q \equiv T

Answer

T2: indirect proof by contrapostion to show  p → q ≡ T p → q ≡ T p 	o q \equiv T
