Proof step 3 from proof pot2-add (previous step)

⊦ 2 ^ (m + n) = 2^ m * 2^ n

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ m ^ (n + n0) = m ^ n * m ^ n0
Proof step 5:
⊦ 2 ^ m * 2 ^ n = 2^ m * 2^ n

Rule argument

spec: inst: name: add seq: ⊦ m ^ (n + n0) = m ^ n * m ^ n0 subst: [n0, n, m] → [n, m, 2] flags: rewrite, current

Additional information

Used terms: n, m, 2
