Theorem genpelxp 6493

Description: Set containing the result of adding or multiplying positive reals. (Contributed by Jim Kingdon, 5-Dec-2019.)

**Hypothesis**
Ref	Expression
genpelvl.1	⊢ 𝐹 = (w ∈ P, v ∈ P ↦ ⟨{x ∈ Q ∣ ∃y ∈ Q ∃z ∈ Q (y ∈ (1^st ‘w) ∧ z ∈ (1^st ‘v) ∧ x = (y𝐺z))}, {x ∈ Q ∣ ∃y ∈ Q ∃z ∈ Q (y ∈ (2^nd ‘w) ∧ z ∈ (2^nd ‘v) ∧ x = (y𝐺z))}⟩)

**Assertion**
Ref	Expression
genpelxp	⊢ ((A ∈ P ∧ B ∈ P) → (A𝐹B) ∈ (𝒫 Q × 𝒫 Q))

Distinct variable groups: x,y,z,w,v,A x,B,y,z,w,v x,𝐺,y,z,w,v Allowed substitution hints: 𝐹(x,y,z,w,v)
