Answer 1

Resposta:

$( \frac{1}{11} + 1) \times ( \frac{1}{12} + 1) \times ( \frac{1}{13} + 1) \times ( \frac{1}{14} + 1) \times ( \frac{1}{15} + 1) \times ( \frac{1}{16} + 1) \times ( \frac{1}{17} + 1) \times ( \frac{1}{18} + 1) \times ( \frac{1}{19} + 1) = \\ ( \frac{1}{11} + \frac{11}{11} ) \times ( \frac{1}{12} + \frac{12}{12} ) \times ( \frac{1}{13} + \frac{13}{13} ) \times ( \frac{1}{14} + \frac{14}{14} ) \times ( \frac{1}{15} + \frac{15}{15} ) \times ( \frac{1}{16} + \frac{16}{16} ) \times ( \frac{1}{17} + \frac{17}{17} ) \times ( \frac{1}{18} + \frac{18}{18} ) \times ( \frac{1}{19} + \frac{19}{19} ) = \\ \frac{12}{11} \times \frac{13}{12} \times \frac{14}{13} \times \frac{15}{14} \times \frac{16}{15} \times \frac{17}{16} \times \frac{18}{17} \times \frac{19}{18} \times \frac{20}{19} = \\ \frac{1}{11} \times \frac{1}{1} \times \frac{1}{1} \times \frac{1}{1} \times \frac{1}{1} \times \frac{1}{1} \times \frac{1}{1} \times \frac{1}{1} \times \frac{20}{1} = \frac{20}{11}$
