1) $frac{2}{x ^{ frac{1}{4} } -y ^{ frac{1}{4} } }+ frac{2}{x ^{ frac{1}{4} }+y ^{ frac{1}{4} } } = frac{2x ^{ frac{1}{4} }+2y ^{ frac{1}{4} } +2x ^{ frac{1}{4} } -2y ^{ frac{1}{4} } }{(x ^{ frac{1}{4} } ) ^{2}-(y ^{ frac{1}{4} }) ^{2} } = frac{4x ^{ frac{1}{4} } }{x ^{ frac{1}{2} }-y ^{ frac{1}{2} } }$
2) $frac{4x ^{ frac{1}{4} } }{x ^{ frac{1}{2} }-y ^{ frac{1}{2} } }* frac{x ^{ frac{1}{2} }-y ^{ frac{1}{2} } }{6x ^{- frac{1}{4} } y ^{- frac{1}{2} } } = frac{2}{3} x ^{ frac{1}{4}} *x ^{ frac{1}{4} }*y ^{ frac{1}{2} }= frac{2x ^{ frac{1}{2} }*y ^{ frac{1}{2} } }{3}= frac{2}{3} sqrt{xy}$
