Proof step 15 from proof test-sqrt-03 (previous step)

37947 ^2 ≤ 1440000000 ∧ 1440000000 < (37947 + 1)^2 ∧ 0 ≤ 37947 → sqrt(1440000000) = 37947 ⊦ sqrt(1440000000) = 37947

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 16:
⊦ sqrt(1440000000) = 37947, 37947 ^2 ≤ 1440000000 ∧ 1440000000 < 37948 ^2
