Theorem rneqi 5012
Description: Equality inference for range. (Contributed by NM, 4-Mar-2004.)
Hypothesis
Ref Expression
rneqi.1 𝐴 = 𝐵
Assertion
Ref Expression
rneqi ran 𝐴 = ran 𝐵

Proof of Theorem rneqi
StepHypRef Expression
1 rneqi.1 . 2 𝐴 = 𝐵
2 rneq 5011 . 2 (𝐴 = 𝐵 → ran 𝐴 = ran 𝐵)
31, 2ax-mp 5 1 ran 𝐴 = ran 𝐵
