Which statement is a wrong reasoning in the proof of (\sqrt{5})?

Answer and explanation

Correct answer: From (p^2=5q^2), we directly get (p=5q)

Step 1: (p^2=5q^2) tells us divisibility of (p^2). Step 2: By the prime rule, (p) is divisible by (5), but (p=5q) does not follow directly. Step 3: In exams, writing (p=5k) is correct.
