AYUDA RÁPIDA POR FAVOR

POR FAVOR :-)

Answer 1

Aplicando teoria de los exponentes sabemos que a

${a}^{m} \div {a}^{n} = {a}^{m - n}$

Entonces:

$( \frac{7}{8} )^{8} \div ( \frac{7}{8})^{6} = ( \frac{7}{8} )^{2} = \frac{49}{64}$

$( \frac{9}{7} )^{6} \div ( \frac{9}{7} )^{4} = (\frac{9}{7} )^{2} = \frac{81}{49}$

$( \frac{7}{4} )^{5} \div ( \frac{7}{4} )^{2} = ( \frac{7}{4} ) ^{3} = \frac{343}{64}$

$(\frac{8}{10} )^{7} \div ( \frac{8}{10} )^{5} = ( \frac{8}{10} )^{2} = \frac{64}{100} = \frac{32}{50} = \frac{16}{25}$
