[tex]2.) \\ (( \frac{5}{2} ) {}^{ - 1}) {}^{ - 2} \\ = ( \frac{5}{2} ) {}^{ - 1 \times - 2} \\ =( \frac{5}{2} ) {}^{2} \\ = \frac{25}{4} [/tex]
Jadi, jawabannya D.

[tex]3.) \\ 3 {}^{ \frac{3}{4} } \\ = \sqrt[4]{3 { }^{3} } \\ = \sqrt[4]{9} [/tex]
Jadi, jawabannya B.

[tex]4.) \\ \sqrt{16 {}^{ \frac{1}{2} } } \\ = \sqrt{4 {}^{2 \times \frac{1}{2} } } \\ = \sqrt{4} \\ = 2[/tex]
Jadi, jawabannya C.

[tex]5.) \\ 5 {}^{8} \div 5 {}^{4} \\ = 5 {}^{8 - 4} \\ = 5 {}^{4} [/tex]
