Proof step 8 from proof sqrt-isSquare (previous step)

⊦ mkDecimal(sqrt((dec0 * dec0).int), (dec0 * dec0).scale / 2) * mkDecimal(sqrt((dec0 * dec0).int), (dec0 * dec0).scale / 2) = dec0 * dec0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ mkDecimal(sqrt((dec * dec).int), (dec * dec).scale / 2) * mkDecimal(sqrt((dec * dec).int), (dec * dec).scale / 2) = dec * dec

Rule argument

spec: decimal-simple-ops inst: name: square-sqrt-01 seq: ⊦ mkDecimal(sqrt((dec * dec).int), (dec * dec).scale / 2) * mkDecimal(sqrt((dec * dec).int), (dec * dec).scale / 2) = dec * dec subst: [dec] → [dec0] flags: rewrite
