Theorem imasival 12892

Description: Value of an image structure. The is a lemma for the theorems imasbas 12893, imasplusg 12894, and imasmulr 12895 and should not be needed once they are proved. (Contributed by Mario Carneiro, 23-Feb-2015.) (Revised by Jim Kingdon, 11-Mar-2025.) (New usage is discouraged.)

Distinct variable groups:   𝐹,𝑝,𝑞   𝑅,𝑝,𝑞   𝑉,𝑝,𝑞   𝜑,𝑝,𝑞

Allowed substitution hints:   𝐵(𝑞,𝑝)   + (𝑞,𝑝)   ✚ (𝑞,𝑝)   ∙ (𝑞,𝑝)   · (𝑞,𝑝)   × (𝑞,𝑝)   𝑈(𝑞,𝑝)   𝑍(𝑞,𝑝)

Proof of Theorem imasival

Dummy variables 𝑓 𝑟 𝑣 are mutually distinct and distinct from all other variables.
