Proof step 9 from proof intshiftrsign-2pot-pos (previous step)

i / 2 i>> (j - 1) = (i / 2) / 2 ^ (j - 1), j < 32, 0 ≤ i, 0 < j, ∀ i, j0. i→n(j0) < i→n(j) → j0 < 32 ∧ 0 ≤ i ∧ 0 < j0 → i i>> j0 = i / 2 ^ j0 ⊦ i / 2 i>> (j - 1) = i / 2 ^ j

Proof step 10:
j < 32, 0 ≤ i, 0 < j, ∀ i, j0. i→n(j0) < i→n(j) → j0 < 32 ∧ 0 ≤ i ∧ 0 < j0 → i i>> j0 = i / 2 ^ j0 ⊦ (i / 2) / 2 ^ (j - 1) = i / 2 ^ j
