Hi,

I am new user of Mathematica 5.2.
Given a List of 50 pairs of elements

{
{ n K / (1-x) , (n+1) (K+1) / (1-0.8 x)},
{ n K / (1-x-y) , (n+1) (K+1) / (1-0.68 x)},
{ n K / (1-x-x) , (n+1) (K+1) / (1-0.78 x)},
..
{ n K / (1-x+y) , (n+1) (K+1) / (1-0.9 (x-y))}

}


I know that

1. n is a positive Integer
2. K is a positive Real.
3. x,y are positive Reals
4. All denominators are positive



Then.. I want

1. To select the Maximum of each pair of expression,

{ n K / (1-x) , (n+1) (K+1) / (1-0.8 x)}



2. If it is not possible (because it is needed to restrict the domain)... may I use Mathematica to restrict or obtain the domain of denominator or other expression that makes that the first or the second is maximum?

3. How could I use the Min[] function in order to computer all the 50 pairs at once?. I am almost sure that is possible to Use Min[] with Apply or something like that.. but I dont know how to proceed.


Thanks in advance,

Lea
