$\longrightarrow{\blue{}}$ $( {216})^{ \frac{ - 2}{3} }$

$\longrightarrow{\blue{}}$ $( {6 \times 6 \times 6})^{ \frac{ - 2}{3} }$

$\longrightarrow{\blue{}}$ $[{ ({6})^{3} }]^{ \frac{ - 2}{3} }$

$\longrightarrow{\blue{}}$ $( {6})^{3 \times \frac{ - 2}{3} }$

$\longrightarrow{\blue{}}$ ${6}^{ - 2}$

$\longrightarrow{\blue{}}$ $\frac{1}{ ({6})^{2} }$

$\longrightarrow{\blue{}}$ $\frac{1}{(6 \times 6)}$

$\longrightarrow{\blue{}}$ $\frac{1}{36}$
