k=0 is an excellent choice.
From the rational root theorem, we have that the square root of any positive integer that is not itself a perfect square, is irrational.

Consider an example with k=1....

Dr. Sardonicus,

Thank you for your input.
I do not see where the equation
{1} sqrt(b^2 - c) = g - f.
comes from.

We start with
sqrt(b+sqrt(c))=sqrt(f)+sqrt(g).
As you pointed out, it...

Also, if c is a perfect square, it simplifies a bit.
