Description: Equality theorem for the range Cartesian product, inference form. (Contributed by Peter Mazsa, 16-Dec-2020.)

Hypothesis

Ref	Expression
xrneq1i.1	⊢ 𝐴 = 𝐵

Assertion

Ref	Expression
xrneq1i	⊢ (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐶)

Proof of Theorem xrneq1i

Step	Hyp	Ref	Expression
1		xrneq1i.1	. 2 ⊢ 𝐴 = 𝐵
2		xrneq1 35663	. 2 ⊢ (𝐴 = 𝐵 → (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐶))
3	1, 2	ax-mp 5	1 ⊢ (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐶)
