Bener kok
Disederhanakan jadi 2^4 . 3^3 . 2^-7 = 27/8

32^{ \frac{4}{5} }  .  \frac{1}3}^{-3} .16^ \frac{-7}{4}  \\ =  \sqrt[5]{32^4} . 3^3. \sqrt[4]{ \frac{1}{16^7}}  \\ = \sqrt[5]{2^{20}}.3^3. \sqrt[4]{ \frac{1}{2^{28}} }    \\ =2^4.3^3. \frac{1}{2^7}  \\  =\frac{3^3}{2^3}   \\ = \frac{27}{8}

udah bener jawabannya
