Description: Equality theorem for the range Cartesian product, deduction form. (Contributed by Peter Mazsa, 18-Dec-2021.)

Hypotheses

Ref	Expression
xrneq12d.1	⊢ (𝜑 → 𝐴 = 𝐵)
xrneq12d.2	⊢ (𝜑 → 𝐶 = 𝐷)

Assertion

Ref	Expression
xrneq12d	⊢ (𝜑 → (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐷))

Proof of Theorem xrneq12d

Step	Hyp	Ref	Expression
1		xrneq12d.1	. 2 ⊢ (𝜑 → 𝐴 = 𝐵)
2		xrneq12d.2	. 2 ⊢ (𝜑 → 𝐶 = 𝐷)
3		xrneq12 39150	. 2 ⊢ ((𝐴 = 𝐵 ∧ 𝐶 = 𝐷) → (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐷))
4	1, 2, 3	syl2anc 596	1 ⊢ (𝜑 → (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐷))
