Proof step 1 from proof test-sqrt-01 (conclusion)

⊦ sqrt(mkDecimal(144, 2)) = mkDecimal(12, 1)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ sqrt(dec) = sqrt(dec, 0)
Proof step 3:
⊦ sqrt(mkDecimal(144, 2), 0) = mkDecimal(12, 1)

Rule argument

spec: inst: name: sqrt-def seq: ⊦ sqrt(dec) = sqrt(dec, 0) subst: [dec] → [mkDecimal(144, 2)] flags: rewrite, current

Additional information

Used terms: mkDecimal(144, 2)
