Theorem pcprod 12276

Description: The product of the primes taken to their respective powers reconstructs the original number. (Contributed by Mario Carneiro, 12-Mar-2014.)

**Hypothesis**
Ref	Expression
pcprod.1	⊢ 𝐹 = (𝑛 ∈ ℕ ↦ if(𝑛 ∈ ℙ, (𝑛↑(𝑛 pCnt 𝑁)), 1))

**Assertion**
Ref	Expression
pcprod	⊢ (𝑁 ∈ ℕ → (seq1( · , 𝐹)‘𝑁) = 𝑁)

Distinct variable group: 𝑛,𝑁 Allowed substitution hint: 𝐹(𝑛)

Proof of Theorem pcprod Dummy variable 𝑝 is distinct from all other variables.
