Step-by-step explanation:

$\huge \sf \frac{4}{ {216}^{ \frac{ - 2}{3} } } - \frac{1}{ {256}^{ \frac{ - 3}{4} } } \\ \\ \large\bf \implies \frac{4}{ {6}(^{ \cancel {3}^ \times { \frac{ - 2}{\cancel3} } } ) } - \frac{1}{ {4}^({ {\cancel4} \times ^{ \frac{ - 3}{\cancel4}) }} } \\ \\ \large\bf \implies \frac{4}{ {6}^{ - 2} } - \frac{1}{ {4}^{ - 3} } \\ \\ \large\bf \implies \frac{4}{ \frac{1}{ {6}^{2} } } - \frac{1}{ \frac{1}{ {4}^{3} } } \\ \\ \large\bf \implies4 \times {6}^{2} - 1 \times {4}^{3} \\ \\\large\bf \implies36 \times 4 - 1 \times 64 \\ \\ \large\bf \implies144 - 64 \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \boxed{\large\bf \implies80} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
