${4}^{ \frac{2}{3} } \times {4}^{2 \frac{1}{5} } \\ = {4}^{ \frac{2}{3} } \times {4}^{ \frac{11}{5} } \\ = {4}^{ \frac{2}{3} + \frac{11}{5} } \\ = {4}^{ \frac{10 + 33}{15} } \\ = {4}^{ \frac{43}{15} } \\ = {4}^{2 \frac{13}{5} }$

$\frac{ {8}^{4} }{ {8}^{ \frac{1}{2} } } = {8}^{4 - \frac{1}{2} } \\ = {8}^{ \frac{8 - 1}{2} } \\ = {8}^{ \frac{7}{2} } \\ = {8}^{3 \frac{1}{2} }$
