jawab nomor 2, dengan caranya

[tex]2.(a) \\ 5 \times (\frac{1}{2} ) {}^{3} \\ 5 \times \frac{1}{8} \\ \frac{5}{8} = 0.625 [/tex]
[tex]2.(b) \\ 14 \times ( \frac{1}{2} ) {}^{ - 3} \\ 14 \times 2 {}^{3} \\ 14 \times 8 \\ 112[/tex]


[tex]( - 6) {}^{2} \times ( - \frac{1}{2} ) {}^{4} \\ {6}^{2} \times \frac{1}{2} {}^{4} \\ {3}^{2} \times {2}^{2} \times {2}^{ - 4} \\ 9 \times {2}^{ - 2} \\ 9 \times \frac{1}{2 {}^{2} } \\ 9 \times \frac{1}{4} \\ \frac{9}{4} = 2.25[/tex]

[tex]( - 3) \times ( - 5) {}^{ - 3} \\ 3 \times \frac{1}{5 {}^{3} } \\ 3 \times \frac{1}{125} \\ \frac{3}{125} = 0.024[/tex]
SEMOGA MEMBANTU :)
