Answer:

${\huge{\blue{\texttt{\orange A\red N\green S\pink W\blue E\purple R\red}}}}$

$= { (- 16)}^{ - 3} \times {( \frac{1}{20} )}^{ - 3}$

$= {\frac{- 1}{16} }^{ - 3} \times {20}^{3}$

$= - \frac{1}{16 \times 16 \times 16} \times 20 \times 20 \times 20$

$- \frac{1}{4 \times 4 \times 4} \times 5 \times 5 \times 5$

$- \frac{125}{64}$

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