Proof step 8 from proof coprime-pot (previous step)

j0 = i1 + 1, gcd(i, j) = 1, i * i0 = j ^ i1 * j, 0 < i, 1 < i, 0 < j0, ∀ j1, i, i0, j. i→n(j1) < i→n(j0) → i * i0 = j ^ j1 ∧ gcd(i, j) = 1 ∧ 0 < i ∧ 1 < i ∧ 0 < j1 → j = 0 ⊦ j = 0

Proof step 9:
gcd(i, j) = 1, i * i0 = j ^ i1 * j, 0 < i, 1 < i, 0 ≤ i1, ∀ j1, i, i0, j. i→n(j1) < i→n(i1 + 1) → i * i0 = j ^ j1 ∧ gcd(i, j) = 1 ∧ 0 < i ∧ 1 < i ∧ 0 < j1 → j = 0 ⊦ j = 0
