Answer 1

$\displaystyle ( \frac{2}{x^{1/4}-y^{1/4}}+ \frac{2}{x^{1/4}+y^{1/4}})* \frac{x^{-1/2}-y^{-1/2}}{6x^{-1/4}y^{-1/2}}= \\ \\ = \frac{2*(x^{1/4}+y^{1/4})+2*(x^{1/4}-y^{1/4})}{x^{1/2}-y^{1/2}}* \frac{y^{1/2}-x^{1/2}}{6x^{-1/4}y^{-1/2}x^{1/2}y^{1/2}}= \\ \\ = -\frac{4x^{1/4}}{6x^{1/4}}= -\frac{2}{3}$
