Answer 1

$cfrac{m-3m^ frac{1}{3} }{m^ frac{2}{3}-3} = cfrac{m^ frac{1}{3}(m^ frac{2}{3}-3) }{m^ frac{2}{3}-3} =m^ frac{1}{3}$

$cfrac{m^ frac{1}{2} -n^ frac{1}{2}}{m^ frac{1}{4}+n^ frac{1}{4}} = cfrac{(m^ frac{1}{4}-n^ frac{1}{4})(m^ frac{1}{4}+n^ frac{1}{4})}{m^ frac{1}{4}+n^ frac{1}{4}} = m^ frac{1}{4}-n^ frac{1}{4}$

$cfrac{x^ frac{1}{3}-2x ^ frac{1}{6}y^ frac{1}{6}+y^ frac{1}{3}}{x^ frac{1}{2}y^ frac{1}{3}-x^ frac{1}{3}y^ frac{1}{2}} = cfrac{(x^ frac{1}{6}-y^ frac{1}{6})^2}{x^ frac{1}{3}y^ frac{1}{3}(x^ frac{1}{6}-y^ frac{1}{6})} = cfrac{x^ frac{1}{6}-y^ frac{1}{6}}{x^ frac{1}{3}y^ frac{1}{3}}$
