Proof step 11 from proof mod-two-ge (previous step)

0 ≤ j, 0 ≤ i0, 0 ≤ i0 + j ⊦ 2 ^ (i0 + j) = 2 ^ i0 * 2 ^ j

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: <toplevel> name: pot-dist-pos seq: ⊦ 0 ≤ j ∧ 0 ≤ j0 → i ^ (j + j0) = i ^ j * i ^ j0 subst: [j0, j, i] → [j, i0, 2] flags: <all paths>
