Найдите значение выражения: 1) \(4\frac{2}{3}\cdot6-1\frac{23}{42}\cdot3\frac{1}{13}+2\frac{1}{8}\cdot1\frac{29}{51}\); 2) \(\left(5\frac{3}{10}-3\frac{4}{5}\cdot\frac{13}{38}\right)\cdot\frac{5}{84}+2\frac{1}{12}\cdot\frac{4}{15}\); 3) \(\left(3\frac{1}{3}\right)^2-2\frac{13}{16}\cdot2\frac{2}{5}\); 4) \(\left(\frac{5}{12}+\frac{13}{20}\right)^2\cdot1\frac{13}{32}\).

1. \(28-\frac{65}{42}\cdot\frac{40}{13}+\frac{17}{8}\cdot\frac{80}{51}=28-\frac{100}{21}+\frac{10}{3}=\frac{186}{7}\).
2. \(\left(\frac{53}{10}-\frac{19}{5}\cdot\frac{13}{38}\right)\cdot\frac{5}{84}+\frac{25}{12}\cdot\frac{4}{15}=4\cdot\frac{5}{84}+\frac{5}{9}=\frac{50}{63}\).
3. \(\left(\frac{10}{3}\right)^2-\frac{45}{8}\cdot\frac{12}{5}=\frac{100}{9}-\frac{27}{2}=-\frac{43}{18}\).
4. \(\left(\frac{25}{60}+\frac{39}{60}\right)^2\cdot\frac{45}{32}=\left(\frac{16}{15}\right)^2\cdot\frac{45}{32}=\frac{8}{5}\).

Ответ: 1) \(\frac{186}{7}\); 2) \(\frac{50}{63}\); 3) \(-\frac{43}{18}\); 4) \(\frac{8}{5}\).
