[tex]( - \frac{3}{10})^{2} - ( - \frac{1}{2} ) ^{2} = \frac{9}{100} - \frac{1}{4} = \frac{4}{25} [/tex]
[tex]( - \frac{1}{6} )^{2} + ( - \frac{2}{3} ) ^{3} = \frac{1}{36} - \frac{8}{27} = - \frac{29}{108} [/tex]
[tex]( - \frac{11}{6} )^{2} + ( - \frac{3}{2} ) ^{3} = \frac{121}{36} - \frac{27}{8} = - \frac{1}{72} [/tex]
