t(n) = number of positive divisors of n
For n => 1, prove that t(n) <= 2sqrt(n)
Hint: If d | n, then one of d or n/d is less than or equal to sqrt(n).
I do not know where to start with this problem. This is a homework question so I just need some assistance getting started with this problem. Also, I'm not sure how to use the hint in this problem. Thanks for your help.
