Description: Equality theorem for the range Cartesian product, inference form. (Contributed by Peter Mazsa, 16-Dec-2020.)
Hypotheses
Ref Expression
xrneq12i.1 𝐴 = 𝐵
xrneq12i.2 𝐶 = 𝐷
Assertion
Ref Expression
xrneq12i (𝐴𝐶) = (𝐵𝐷)

Proof of Theorem xrneq12i
StepHypRef Expression
1 xrneq12i.1 . 2 𝐴 = 𝐵
2 xrneq12i.2 . 2 𝐶 = 𝐷
3 xrneq12 36440 . 2 ((𝐴 = 𝐵𝐶 = 𝐷) → (𝐴𝐶) = (𝐵𝐷))
