Proof step 1 from proof square-neq-any-pos-02 (conclusion)
0 < i, 0 < j, 0 < j0, gcd(j, j0) = 1, j * j = i * j0 * j0 ⊦ ∃ i0. i = i0 * i0
System applied rule normalize
And obtained the following new goals
Proof step 2
:
j * j = i * j0 * j0, gcd(j, j0) = 1, 0 < j0, 0 < j, 0 < i ⊦ ∃ i0. i = i0 * i0
Rule argument
