Proof step 6 from proof test-sqrt-02 (previous step)

even(mkDecimal(2, 0).scale) ⊦ mkDecimal(sqrt(mkDecimal(2, 0).int * 10 ^ (2 * abs(2))), mkDecimal(2, 0).scale / 2 + abs(2)) = mkDecimal(141, 2)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
even(mkDecimal(2, 0).scale) ⊦ mkDecimal(sqrt(mkDecimal(2, 0).int * 10000), mkDecimal(2, 0).scale / 2 + 2) = mkDecimal(141, 2)
