[tex]a) \: \: \: ( - \frac{2}{5}) {}^{2} \\ \\ ( \frac{2}{5} ) {}^{2} \\ \\ \frac{2 {}^{2} }{5 {}^{2} } \\ \\ \frac{4}{5 {}^{2} } \\ \\ \frac{4}{25} \\ \\ [/tex]

[tex] b) \: \: \: ( - \frac{11}{2})^{3} \\ \\ - ( \frac{11}{2} ) {}^{3} \\ \\ - \frac{11 {}^{3} }{2 {}^{3} } \\ \\ - \frac{1331}{2 {}^{3} } \\ \\ - \frac{1331}{8} \\ \\ [/tex]

[tex]c) \: \: ( + \frac{1}{3} ) \\ \\ 3 {}^{1} [/tex]

[tex]d) \: \: ( + \frac{1}{2} ) {}^{5} \\ \\ \frac{1 {}^{5} }{2 {}^{5} } \\ \\ \frac{1}{2 {}^{5} } \\ \\ \frac{1}{32} [/tex]
