Theorem fsumconst 11462

Description: The sum of constant terms (𝑘 is not free in 𝐵). (Contributed by NM, 24-Dec-2005.) (Revised by Mario Carneiro, 24-Apr-2014.)

**Assertion**
Ref	Expression
fsumconst	⊢ ((𝐴 ∈ Fin ∧ 𝐵 ∈ ℂ) → Σ𝑘 ∈ 𝐴 𝐵 = ((♯‘𝐴) · 𝐵))

Distinct variable groups: 𝐴,𝑘 𝐵,𝑘

Proof of Theorem fsumconst Dummy variables 𝑤 𝑦 𝑧 are mutually distinct and distinct from all other variables.
