Proof step 9 from proof max_exp-fac-01 (previous step)

j0 < i, prime(i), 1 < i, 0 < i, 0 < j0, ∀ j, i. i→n(j) < i→n(j0) → prime(i) ∧ j < i ∧ 0 ≤ j ∧ 0 < i → max_exp(i, fac(i + j)) = 1 ⊦ j0 = 0, max_exp(i, (i + j0) * fac(i + j0 - 1)) = 1

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: inst: name: max_exp-mult seq: ⊦ 0 < j ∧ 0 < j0 ∧ prime(i) → max_exp(i, j * j0) = max_exp(i, j) + max_exp(i, j0) subst: [j0, j, i] → [fac(i + j0 - 1), i + j0, i] flags: rewrite, current
