    If we were to factor 34! what power of five, 5^K, would be in the factorization?
    That is your answer.

    "0"s at the end of a number mean there are factors of 10. k "0"s at the end of a number mean there are k factors of 10 in the number. How many "2"s, "5"s, and "10"s are multiplied in 34! ? (it is sufficent to count the factors of "5".)
