Homework Statement
I would like to prove that when x is between 1 and 2 [tex] \frac{k^{0.5}x^x}{1+x^{2k}} < \frac{1}{\sqrt{x-1}} [/tex] for all [itex] k\in \mathbb{N} [/itex]

The Attempt at a Solution
This is for my analysis class. I am algebraist, so please take pity :)
I have learned that if I were to show that the numerator of the first fraction is less than the numerator of the second and the denominator of the first fraction is greater than the denominator of the second then the first fraction would be smaller than the second. That technique doesn't seem to be working though. If the second fraction needs tweaking to make this work then that is fine. I'm just trying to bound the first fraction with something integrable. I think my bound works based on Maple graphs.
