Theorem relexpaddss 38512
Description: The composition of two powers of a relation is a subset of the relation raised to the sum of those exponents. This is equality where 𝑅 is a relation as shown by relexpaddd 13993 or when the sum of the powers isn't 1 as shown by relexpaddg 13992. (Contributed by RP, 3-Jun-2020.)
