Raspuns:

$( - \frac{2}{5} ) {}^{4} \div ( \frac{2}{5}) {}^{2} - 8 \times (2 - \frac{2}{3} \times 1 \frac{2}{3} )$

$( \frac{2}{5} ) {}^{4} \div ( \frac{2}{5} ) {}^{2} - 8 \times (2 - \frac{10}{9} )$

$( \frac{2}{5} ) {}^{2} - 8 \times \frac{8}{9}$

$\frac{4}{25} - \frac{64}{9}$

$- \frac{1564}{225}$
