|---|---|
| fvconst2.1 | ⊢ 𝐵 ∈ V |
| Ref | Expression |
|---|---|
| fconst2 | ⊢ (𝐹:𝐴⟶{𝐵} ↔ 𝐹 = (𝐴 × {𝐵})) |
| Step | Hyp | Ref | Expression |

| 1 | fvconst2.1 | . 2 ⊢ 𝐵 ∈ V | |
| 2 | fconst2g 7209 | . 2 ⊢ (𝐵 ∈ V → (𝐹:𝐴⟶{𝐵} ↔ 𝐹 = (𝐴 × {𝐵}))) | |
| 3 | 1, 2 | ax-mp 5 | 1 ⊢ (𝐹:𝐴⟶{𝐵} ↔ 𝐹 = (𝐴 × {𝐵})) |
