\[1)\ \left( \frac{1}{2} \right)^{4} = \frac{1}{2} \cdot \frac{1}{2} \cdot \frac{1}{2} \cdot \frac{1}{2} = \frac{1}{4} \cdot \frac{1}{4} =\]
\[= \frac{1}{16}\]
\[2)\ \left( \frac{2}{5} \right)^{3} = \frac{2}{5} \cdot \frac{2}{5} \cdot \frac{2}{5} = \frac{4 \cdot 2}{25 \cdot 5} =\]
\[= \frac{8}{125}\]
\[3)\ \left( 1\frac{1}{3} \right)^{4} = \left( \frac{4}{3} \right)^{4} = \frac{4}{3} \cdot \frac{4}{3} \cdot \frac{4}{3} \cdot \frac{4}{3} =\]
\[= \frac{16}{9} \cdot \frac{16}{9} = \frac{256}{81} = 3\frac{13}{81}\]
