[tex]hasil \: dari( {243}^{2})^{ - \frac{1}{5 \: } } \: adalah[/tex]

[tex] = (243 {}^{2} ) {}^{ - \frac{1}{5} } [/tex]

[tex] = (243){}^{2 \times - \frac{1}{5} } [/tex]

[tex] = 243 {}^{ - \frac{2}{5} } [/tex]

[tex] = \frac{1}{243 {}^{ \frac{2}{5} } } [/tex]

[tex] = \frac{1}{( {3}^{5}) {}^{ \frac{2}{5} } } [/tex]

[tex] = \frac{1}{ {3}^{2} } [/tex]

[tex] = \frac{1}{9} [/tex]

Jadi, hasilnya adalah 1/9
