Thực hiện phép tính: \[160:\left\{ {64-\left[ {50:2-\left( {{3^2}-2{\rm{ }}.{\rm{ }}4} \right)} \right]} \right\}\].

\[160:\left\{ {64--\left[ {50:2--\left( {{3^2}--2{\rm{ }}.{\rm{ }}4} \right)} \right]} \right\}\]

\[ = 160:\left\{ {64--\left[ {50:2--\left( {9--8} \right)} \right]} \right\}\]

\[ = 160:\left\{ {64--\left[ {25--1} \right]} \right\}\]

\[ = 160:\left\{ {64--24} \right\}\]

\[ = 160:40 = 4.\]
