(4/9)pangkat 1/2 +(8/27)pangkat 1/3+(16/81)pangkat 1/4

[tex] { \frac{4}{9} }^{ \frac{1}{2} } + { \frac{8}{27} }^{ \frac{1}{3} } + { \frac{16}{81} }^{ \frac{1}{4} } = \sqrt[2]{ \frac{4}{9} } + \sqrt[3]{ \frac{8}{27} } + \sqrt[4]{ \frac{16}{81} } \\ \\ = \frac{2}{3} + \frac{2}{3} + \frac{2}{3} = \frac{6}{3} = 2[/tex]
