A) \[\frac{9}{2}\]
B) \[\frac{2}{9}\]
C) \[{{\left( \frac{2}{3} \right)}^{8}}\]
D) \[\frac{27}{8}\]
Correct Answer: C
Solution :
\[\frac{16}{81}=\frac{{{2}^{4}}}{{{3}^{4}}}={{\left( \frac{2}{3} \right)}^{4}}\]\[\Rightarrow \] \[{{\left( \frac{16}{81} \right)}^{2}}={{\left[ {{\left( \frac{2}{3} \right)}^{4}} \right]}^{2}}={{\left( \frac{2}{3} \right)}^{8}}\]
