Question

2. Вычислите. а)7/9-1/3-5/18 b) 7/8-1/3-1/6 c) 3/5-3/10-2/15 d) 5/6-3/9-5/12​

Answer 1

Ответ:

а)$\frac{7} {9} ^{2} - \frac{1}{3}^{6} - \frac{5}{18} = \frac{14}{18} - \frac{6}{18} - \frac{5}{18} = \frac{3}{18} = \frac{1}{6}$

б)$\frac{7}{8} ^{3} - \frac{1}{3} ^{8} - \frac{1}{6} ^{4} = \frac{21}{24} - \frac{8}{24} - \frac{4}{21} = \frac{9}{21} = \frac{3}{7}$

с)$\frac{3}{5}^{6} - \frac{3}{10}^{3} - \frac{2}{15}^{2} = \frac{18}{30} - \frac{9}{30} - \frac{4}{30} = \frac{5}{30} = \frac{1}{6}$

d)$\frac{5}{6} ^{6} - \frac{3}{9} ^{4} - \frac{5}{12} ^{3} = \frac{30}{36} - \frac{12}{36} - \frac{15}{36} = \frac{3}{36} = \frac{1}{12}$
