Which statement gives the correct basis for writing (p=3k) in the proof of (\sqrt{3})?
Answer and explanation
Correct answer: (p^2) is divisible by (3) and (3) is prime
Step 1: From (p^2=3q^2), (p^2) is divisible by (3). Step 2: Since (3) is prime, (p) is also divisible by (3). Step 3: Therefore writing (p=3k) is valid.
