Ответ:
- \(\frac{7!-5!}{5!}=\frac{7\cdot6\cdot5!-5!}{5!}=42-1=41\).
- \(\frac{6!-4!}{5!}=\frac{6\cdot5!-4!}{5!}=6-\frac{1}{5}=\frac{29}{5}\).
- \(\frac{149!}{148!}-\frac{36!}{35!}=149-36=113\).
- \(\frac{97!}{96!}+\frac{35!}{34!}=97+35=132\).
- \(\frac{4!\cdot8!}{6!\cdot7!}=\frac{4!\cdot8\cdot7!}{6\cdot5!\cdot7!}=\frac{4!\cdot8}{6!}=\frac{192}{720}=\frac{4}{15}\).
- \(\frac{9!\cdot5!}{7!\cdot6!}=\frac{9\cdot8\cdot7!\cdot5!}{7!\cdot6\cdot5!}=\frac{72}{6}=12\).
Ответ: 1) 41; 2) \(\frac{29}{5}\); 3) 113; 4) 132; 5) \(\frac{4}{15}\); 6) 12.
