\[\boxed{\text{141\ (141).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]

\[1)\ \left( \frac{1}{3} \right)^{5} = \frac{1^{5}}{3^{5}} = \frac{1}{243}.\]

\[2)\ \left( \frac{2}{5} \right)^{3} = \frac{2^{3}}{5^{3}} = \frac{8}{125}.\]

\[3)\ \left( - 2\frac{2}{3} \right)^{2} = \left( - \frac{8}{3} \right)^{2} =\]

\[= \frac{( - 8)^{2}}{3^{2}} = \frac{64}{9} = 7\frac{1}{9}.\]

\[4)\ \left( - 3\frac{1}{3} \right)^{3} = \left( - \frac{10}{3} \right)^{3} =\]

\[= \frac{( - 10)^{3}}{3^{3}} = - \frac{1000}{27} = - 37\frac{1}{27}.\]
