Proof step 2 from proof power-of-2 (previous step)

⊦ 2 * 2 ^ m / 2 = 2 ^ m, 2 ^ m = 1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
n ≠ 0 ⊦ m % n = 0 → m / n * n = m

Rule argument

spec: nat-div inst: name: mult-02 seq: n ≠ 0 ⊦ m % n = 0 → m / n * n = m subst: [n, m] → [2, 2 ^ m] flags: rewrite

Additional information

Used simplifier rules: 2-pot-mod-01: ⊦ 2 ^ m ≠ 1 → 2 ^ m % 2 = 0;%mult-c: ⊦ m * n = n * m; from specification nat-mult Used terms: 2, 2 ^ m
