$1)x^{\frac{11}{18}}:x^{-\frac{5}{6}}=x^{\frac{11}{18}-(-\frac{5}{6})}=x^{\frac{11}{18}+\frac{15}{18} }=x^{\frac{26}{18}}=\boxed{x^{\frac{13}{9}}}\\\\\\2)(x^{\frac{2}{3}}y^{\frac{2}{9}})^{\frac{18}{25}}=x^{\frac{2}{3}*\frac{18}{25}}y^{\frac{2}{9}*\frac{18}{25}}=\boxed{x^{\frac{12}{25}}y^{\frac{4}{25}}}$
