There are 5 factors of in the numerator and 8 factors of in the denominator -- eliminate the 5 factors of in the numerator and all but 3 of them in the denominator. There are 7 factors of in the numerator, and 5 in the denominator. Eliminate all of them in the denominator and all but 2 of them in the numerator. Finally there are 3 factors of in each of the numerator and denominator. They can all go away. So: John
