Jawaban:
a.
[tex]( - 16) \times ( - 3) - ( - 8) \times 5 \\ = (( - 16) \times ( - 3)) - (( - 8) \times 5) \\ = 48 - ( - 40) \\ = 88[/tex]
b.
[tex]( - 2 + ( - 7)) {}^{3} \\ = ( - 9) {}^{3} \\ = - 729[/tex]
c.
[tex]3 \frac{1}{2} \times ( - 5 \frac{1}{7} ) \div (1 \frac{4}{5}) \\ = \frac{7}{2} \times ( - \frac{36}{7} ) \div ( \frac{9}{5} ) \\ = - \frac{252}{14} \div ( \frac{9}{5} ) \\ = \frac{252}{14} \times \frac{5}{9} \\ = \frac{1.260}{126} \\ = 10[/tex]
d.
[tex] \frac{2}{3} \times ( \frac{1}{4} - \frac{1}{8} ) {}^{2} \\ = \frac{2}{3} \times( \frac{2}{8} - \frac{1}{8} ) {}^{2} \\ = \frac{2}{3} \times ( \frac{1}{8} ) {}^{2} \\ = \frac{2}{3} \times \frac{1}{64} \\ = \frac{1}{96} [/tex]
Semoga benar dan membantu yaaa...
