Explicație pas cu pas:

1)

$\frac{5}{6} \div \Big( \frac{4}{6} \div \frac{8}{3} \Big)$

$= \frac{5}{6} \div \Big( \frac{ \not 4}{ \not 6 } \times \frac{ \not3}{ \not8} \Big)$

$= \frac{5}{6} \div \Big( \frac{1}{2} \times \frac{1}{2} \Big)$

$= \frac{5}{6} \div \frac{1}{4}$

$= \frac{5}{6} \times 4 = \frac{20 {}^{(2} }{6} = \boxed{ \frac{10}{3}}$

2)

$\Big(\frac{ {}^{2)} 1}{2} + \frac{1}{4} \Big) \times 8$

$= \Big( \frac{2}{4} + \frac{1}{4} \Big) \times 8$

$= \frac{3}{4} \times 8 = \frac{24}{4} = \boxed{6}$

3)

$\frac{3 {}^{4} }{ {2}^{3} } \div \Big( \frac{3}{2} \Big) {}^{4}$

$= \frac{3 {}^{4} }{2 {}^{3} } \div \frac{3⁴}{2⁴}$

$= \frac{ \not3 {}^{4} }{2 {}^{ \not3} } \times \frac{2 {}^{ \not4} }{ \not 3 {}^{4} } = \boxed{2}$
