What will man be like in 5,000 or even 50,000 year from now on We can only make a guess, of course. However, we can be sure that he will greatly differ from what he is today. 36 Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today...
Does every number have a prime factorization? Determine what positive integer below 50,000 has the most proper divisors, and determine how many divisors that number has. Do complex numbers have zero-divisors? Every positive integer greater than 1 has at least two divisors and can be written as...
