Proof step 13 from proof split-unique (previous step)

2 * m0 + 1 = lead(m) * 2 ^ #fz(m), ∀ n0, m. n0 < m0 + m0 → (lead(n0) * 2 ^ #fz(n0) = lead(m) * 2 ^ #fz(m) → m = n0) ⊦ m = 2 * m0

User applied rule cut formula

And obtained the following new goals

Proof step 7:
even(m), 2 * m0 + 1 = lead(m) * 2 ^ #fz(m), ∀ n0, m. n0 < m0 + m0 → (lead(n0) * 2 ^ #fz(n0) = lead(m) * 2 ^ #fz(m) → m = n0) ⊦ m = 2 * m0
Proof step 12:
2 * m0 + 1 = lead(m) * 2 ^ #fz(m), ∀ n0, m. n0 < m0 + m0 → (lead(n0) * 2 ^ #fz(n0) = lead(m) * 2 ^ #fz(m) → m = n0) ⊦ even(m), m = 2 * m0

Rule argument

[fma-arg: even(m)]
