Hi all,

This is my first post so treat me well ! :-)

Total newbie to Mathematica.

I just want to see the Real numbers solutions, not complex for the following:

Solve[{105.687 == 5/(1 + rreal1),
109.595 == 5/(1 + rreal1) + 5/(1 + rreal2)^2 + 105/(1 + rreal3)^3,
112.984 ==
5/(1 + rreal1) + 5/(1 + rreal2)^2 + 5/(1 + rreal3)^3 +
5/(1 + rreal4)^4 +
105/(1 + rreal5)^5, (1 + rreal2)^2/(1 + rreal1) == (1 +
rreal3)^3/(1 + rreal2)^2, (1 + rreal4)^4/(1 + rreal3)^3 == (1 +
rreal5)^5/(1 + rreal4)^4 }, {rreal1, rreal2, rreal3, rreal4,
rreal5}]

But the result solutions is tooooo big. I have try the "Reduce" and "DeleteCases" options from this post, but they don't work!.

What I am doing wrong ?
