Theorem frlmelbas 21311

Description: Membership in the base set of the free module. (Contributed by Stefan O'Rear, 1-Feb-2015.) (Revised by AV, 23-Jun-2019.)

**Hypotheses**
Ref	Expression
frlmval.f	⊢ 𝐹 = (𝑅 freeLMod 𝐼)
frlmelbas.n	⊢ 𝑁 = (Base‘𝑅)
frlmelbas.z	⊢ 0 = (0_g‘𝑅)
frlmelbas.b	⊢ 𝐵 = (Base‘𝐹)

**Assertion**
Ref	Expression
frlmelbas	⊢ ((𝑅 ∈ 𝑉 ∧ 𝐼 ∈ 𝑊) → (𝑋 ∈ 𝐵 ↔ (𝑋 ∈ (𝑁 ↑_m 𝐼) ∧ 𝑋 finSupp 0 )))

Proof of Theorem frlmelbas Dummy variable 𝑘 is distinct from all other variables.
