Proof step 13 from proof test-sqrt-05 (previous step)

odd(5) ⊦ sqrt(mkDecimal(29, 5).int * 10000000) = 17029

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 14:
⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i
Proof step 15:
¬(29 % 10 = 0 ∧ 5 ≠ 0 ∧ 29 ≠ 0), odd(5) ⊦ sqrt(29 * 10000000) = 17029

Rule argument

spec: decimal inst: name: intvalue-base seq: ⊦ ¬(i % 10 = 0 ∧ j ≠ 0 ∧ i ≠ 0) → mkDecimal(i, j).int = i subst: [j, i] → [5, 29] flags: rewrite
