nomor 13.) [ opsi. A ]

≡ penyelesaian :
[tex] = ( {125}^{2} )^{ - \frac{1}{3} } \\ \\ = {125}^{ - \frac{2}{3} } \\ \\ = ( {5}^{3} ) {}^{ - \frac{2}{3} } \\ \\ = \frac{1}{( {5}^{3} ) {}^{ \frac{2}{3} } } \\ \\ = \frac{1}{ {5}^{2} } \\ \\ = \frac{1}{25} [/tex]

nomor 14.) [ opsi. B ]

≡ penyelesaian :
[tex] = ( {64}^{ - \frac{1}{4}) {}^{ \frac{2}{3}}} \\ \\ = {64}^{ - \frac{1}{6} } \\ \\ = ({2}^{6} ) {}^{ - \frac{1}{6} } \\ \\ = \frac{1}{( {2}^{6}) {}^{ \frac{1}{6} } } \\ \\ = \frac{1}{( {2})^{1} } \\ \\ = \frac{1}{2} [/tex]
