plis, ayuda :"v!!! no lo entiendo :"v los esponentes en Q :""v ​

Answer 1

$( \frac{5}{8}) {}^{3} .( \frac{2}{5} ) {}^{4} \\ ( \frac{5}{8} ) {}^{3} \times ( \frac{2}{5}) {}^{3} \times \frac{2}{5} \\ ( \frac{5}{8} \times \frac{2}{5} ) {}^{3} \times \frac{2}{5} \\ reducimos \: los \: 5 \: usando \: como \: divisor \\ ( \frac{1}{8} \times 2) {}^{3} \times \frac{2}{5} \\ reducimos \: a \: 8 \: usando \: como \: divisor \: el \: 2 \\ ( \frac{1}{4}) {}^{3} \times \frac{2}{5} \\ reorganizamos \\ \frac{2}{5} \times ( \frac{1}{4} ) {}^{3} \\ elevamos \: a \: la \: potencia \: de \: 3 \\ \frac{2}{5} \times \frac{1}{64} \\ reducimos \: a \: 2 \\ \frac{1}{5} \times \frac{1}{32} \\ multiplicas \\ \frac{1}{160} = 0.00625$

$( \frac{2}{3} ) {}^{4} \times (\frac{2}{3} ) {}^{4} \\ ( \frac{2}{3} ) ^{4} + {}^{4} \\ ( \frac{2}{3} ) {}^{8} \\ \frac{2 {}^{8} }{3 {}^{8} } \\ \frac{256}{6561} = 0.0390184$

$(( \frac{3}{7} ) {}^{4} ) {}^{5} \\ ( \frac{3}{7} ) {}^{20} \\ \frac{3 {}^{20} }{7 {}^{20} } = 4.36983 \times 10 {}^{ - 8}$

espero que te sirva me costó mucho
