Theorem iundisj 23316

Description: Rewrite a countable union as a disjoint union. (Contributed by Mario Carneiro, 20-Mar-2014.)

Hypothesis

Ref	Expression
iundisj.1	⊢ (𝑛 = 𝑘 → 𝐴 = 𝐵)

Assertion

Ref	Expression
iundisj	⊢ ∪ 𝑛 ∈ ℕ 𝐴 = ∪ 𝑛 ∈ ℕ (𝐴 ∖ ∪ 𝑘 ∈ (1..^𝑛)𝐵)

Distinct variable groups:   𝑘,𝑛   𝐴,𝑘   𝐵,𝑛

Allowed substitution hints:   𝐴(𝑛)   𝐵(𝑘)

Proof of Theorem iundisj

Dummy variables 𝑥 𝑚 are mutually distinct and distinct from all other variables.
