$\frac{2}{3}$

Пошаговое объяснение:

$( \frac{2}{3} ) {}^{3} (4 \frac{1}{5} - 3 \frac{7}{10} ) {}^{2} = \\ = ( \frac{2}{3} ) {}^{3} ( \frac{21}{5} - \frac{37}{10} ) {}^{2} = \\ = \frac{8}{27} ( \frac{2 \times 21}{2 \times 5} - \frac{37}{10} ) {}^{2} = \\ = \frac{8}{27} ( \frac{42 - 37}{10} ) {}^{2} = \\ = \frac{8}{27} ( \frac{15}{10} ) {}^{2} = \\ = \frac{8}{27} \times \frac{225}{100} = \\ = \frac{1800}{2700} = \\ = \frac{900 \times 2}{900 \times 3} = \frac{2}{3}$
