# Conjugation on limit

Calculus Level 1

$\large \lim_{x\to\infty}\left( \sqrt{x +\sqrt{x}} - \sqrt{x}\right), \quad \lim_{x\to\infty}\left( \sqrt{x +\sqrt{x +\sqrt{x}}} - \sqrt{x}\right)$

It is possible to show that both the limits above are equal to $\frac12.$

Is it true that the limit below is also equal to $\frac12?$

$\lim_{x\to\infty}\left(\sqrt{x+ \sqrt{x +\sqrt{x +\sqrt{x}}}} - \sqrt{x}\right)$
