hitunglah dan tuliskan sampai2 tempat desimal .8^-1/5/8^3/4

[tex] \frac{8^{ -\frac{1}{5} }}{8^{ \frac{3}{4} } } \\ = \frac{ \frac{1}{8^{ \frac{1}{5} }} }{8^{ \frac{3}{4} } } \\ = \frac{1}{8^{ \frac{1}{5} }\times 8^{ \frac{3}{4} }} \\ = \frac{1}{ 8^{( \frac{1}{5} + \frac{3}{4} )} } \\ = \frac{1}{ 8^{ \frac{4+15}{20}} } \\ = \frac{1}{ 8^{ \frac{19}{20}} } \\ = 8^{-\frac{19}{20}} \\ [/tex]
