Proof step 16 from proof pot-isSquare (previous step)

isSquare(i) ∨ even(j), 0 < i, 0 < j ⊦ isSquare(i ^ j)

User applied rule cut formula

And obtained the following new goals

Proof step 17:
isSquare(i), isSquare(i) ∨ even(j), 0 < i, 0 < j ⊦ isSquare(i ^ j)
Proof step 24:
isSquare(i) ∨ even(j), 0 < i, 0 < j ⊦ isSquare(i), isSquare(i ^ j)

Rule argument

fma: isSquare(i)
