Hi, I am studying a paper by Yann Bugeaud (click here), on page 13 there is an inequality (16) as given below-

which is obtained from -

attachment.php


, on page 12.

How the inequality (16) is derived? I couldn't figure it out. However one of my forum member

tried but it has two problems (problems are marked as "how?"), it is given below-

attachment.php


It is not clear how those two questions would be resolved.

Can any one show the derivation of inequality (16)?




Thanks in Advance.
