Proof step 18 from proof test-sqrt-04 (previous step)

5385 ^2 ≤ 29000000 ∧ 29000000 < (5385 + 1)^2 ∧ 0 ≤ 5385 → sqrt(29000000) = 5385, even(4) ⊦ sqrt(29000000) = 5385

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 19:
even(4) ⊦ sqrt(29000000) = 5385, 5385 ^2 ≤ 29000000 ∧ 29000000 < 5386 ^2
