Theorem psrbaspropd 21451

Description: Property deduction for power series base set. (Contributed by Stefan O'Rear, 27-Mar-2015.)

**Hypothesis**
Ref	Expression
psrbaspropd.e	⊢ (𝜑 → (Base‘𝑅) = (Base‘𝑆))

**Assertion**
Ref	Expression
psrbaspropd	⊢ (𝜑 → (Base‘(𝐼 mPwSer 𝑅)) = (Base‘(𝐼 mPwSer 𝑆)))

Proof of Theorem psrbaspropd Dummy variable 𝑎 is distinct from all other variables.
