Answer 1

Explicație pas cu pas:

2.

$\frac{3 {}^{6} }{4} - \frac{7 {}^{3} }{8} + \frac{1 {}^{4} }{6} - \frac{2 {}^{8} }{3} = \\ \frac{18}{24} - \frac{21}{24} + \frac{4}{24} - \frac{16}{24} = \frac{ - 15}{24} \\ 3. \: \frac{5 {}^{3} }{4} - \frac{ {5}^{4} }{3} + \frac{ {1}^{6} }{2} - \frac{ {1}^{4} }{3} = \\ \frac{15}{12} - \frac{20}{12} + \frac{6}{12} - \frac{4}{12} = \frac{ - 3}{12}$
