Решите задачу:

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

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

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