Which of the following is the correct ppp-adic absolute value property?
∣xy∣p=∣x∣p+∣y∣p|xy|_p = |x|_p + |y|_p∣xy∣p=∣x∣p+∣y∣p
∣xy∣p=∣x∣p⋅∣y∣p|xy|_p = |x|_p \cdot |y|_p∣xy∣p=∣x∣p⋅∣y∣p
∣x+y∣p=∣x∣p+∣y∣p|x + y|_p = |x|_p + |y|_p∣x+y∣p=∣x∣p+∣y∣p
∣xy∣p=max(∣x∣p,∣y∣p)|xy|_p = \max(|x|_p, |y|_p)∣xy∣p=max(∣x∣p,∣y∣p)
