Penyelesaian :
[tex] {32}^{ \frac{2}{5} } - {81}^{ \frac{1}{4} } \\ = \sqrt[5]{ {32}^{2} } - \sqrt[4]{ {81}^{1} } \\ = \sqrt[5]{1024} - \sqrt[4]{81} \\ = 4 - 3[/tex]
= 1

Maaf kalau salah

[tex] = {32}^{ \frac{2}{5} } - {81}^{ - \frac{1}{4} } \\ \\ = ( {2}^{5} )^{ \frac{2}{5}} - ( {3}^{4} )^{ - \frac{1}{4} } \\ \\ = {2}^{2} - \frac{1}{( {3}^{4})^{ \frac{1}{4} } } \\ \\ = 4 - \frac{1}{3} \\ \\ = \frac{12 - 1}{3} = \frac{11}{3} = 3 \frac{2}{3} = 3,67[/tex]
