Answer 1

Respuesta:

${5}^{ - 1} + {4}^{ - 1} - {3}^{ - 1} + {6}^{ - 1} = \frac{1}{5} + \frac{1}{4} - \frac{1}{3} + \frac{1}{6} = \frac{12}{60} + \frac{15}{60} - \frac{20}{60} + \frac{10}{60} = \frac{17}{60}$

$\frac{ {2}^{ - 1} - {3}^{ - 1} }{ {3}^{ - 1} + {2}^{ - 1} } = \frac{ \frac{1}{2} - \frac{1}{3} }{ \frac{1}{3} + \frac{1}{2} } = \frac{ \frac{3 - 2}{6} }{ \frac{2 + 3}{6} } = \frac{ \frac{1}{6} }{ \frac{5}{6} } = \frac{1}{6} \div \frac{5}{6} = \frac{1 \times 6}{6 \times 5} = \frac{6}{30} = \frac{1}{5} = {5}^{ - 1}$

${2}^{ - 1} \times {4}^{3} = \frac{1}{2} \times 64 = \frac{64}{2} = 32 = {2}^{5}$

$14 \times {2}^{ - 3} - 6 \times {2}^{ - 3} = 14 \times \frac{1}{8} - 6 \times \frac{1}{8} = \frac{14}{8} - \frac{6}{8} = \frac{8}{8} = 1$
