Proof step 5 from proof div (previous step)

∃ j0. i = j0 * j ⊦ (i / j)^2 = i ^2 / j ^2, j = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
⊦ j0 ^2 = (j0 * j)^2 / j ^2, j = 0

Rule argument

Additional information

Used simplifier rules: commutativity: ⊦ i * j = j * i; from specification int-mult%associativity: ⊦ i * j * j0 = (i * j) * j0; from specification int-mult%j ≠ 0 ⊦ (i * j) / j = i; (s)
