Let x and y be positive integers such that the prime factorization of x has exactly four 5’s and prime factorization of y has exactly two 5’s. How many 5’s does the prime factorization of x + y contain? (Hint: the assumption described in the first sentence means that x = 54a and y = 52b where a and b are integers that are not divisible by 5 )
