Answer 2

Answer:

$(i) \frac{ - 27}{32}$

$(ii) \frac{973}{324}$

Step-by-step explanation:

$( { \frac{ - 1}{2} )}^{5} \times {2}^{6} \times { (\frac{3}{4}) }^{3}$

$\frac{ { - 1}^{5} }{ {2}^{5} } \times {2}^{6} \times \frac{ {3}^{3} }{ {4}^{3} }$

$\frac{ - 1}{ {2}^{5} } \times {2}^{6} \times \frac{ 27 }{64}$

$- 1 \times 2 \times \frac{27}{64}$

$- 2 \times \frac{27}{64}$

$\frac{ - 27}{32}$

-----------------------------------------------------------------------------------

(ii)

$(( \ { \frac{ - 3}{4}) }^{3} - {( \frac{ - 5}{2} )}^{3} ) \times { ( - \frac{2}{3}) }^{4}$

$(( \frac{ { - 3}^{3} }{ {4}^{3} } ) - ( \frac{ { - 5}^{3} }{ {2}^{3} } )) \times ( \frac{ { - 2}^{4} }{ {3}^{4} } )$

$(( \frac{ - 27}{64} ) - ( \frac{ - 125}{8} )) \times (\frac{16}{81} )$

$( \frac{ - 27}{64} + \frac{125}{8} ) \times \frac{16}{81}$

$( \frac{ - 27 + (125 \times 8)}{64} ) \times \frac{16}{81}$

$( \frac{ - 27 + 1000}{64} ) \times \frac{16}{81}$

$\frac{973}{64} \times \frac{16}{81}$

$\frac{973}{4 \times 81}$

$\frac{973}{324}$
