Date: 12/08/2002 at 13:41:12 From: Doctor Ian Subject: Re: Math Hi Brendan, Write out the prime factorization for 735. Note that the prime factorization of a perfect cube must look like n m 3 (a b ...) What prime factors would you have to add to get something like that? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ |
