Answer 1

Bună ziua! Eu propun această rezolvare !

${(( \frac{3}{5}) }^{6} )^{10} = (( \frac{9}{25} )^{5} )^{n} \\ ( \frac{3}{5} ) ^{60} = ( \frac{3}{5} )^{10n} \\ \\ 60 = 10n \\ n = 6$

Answer 2

Salut,

$[( \frac{3}{6} ) {}^{6} ] {}^{10} = [( \frac{9}{25} ) {}^{5} ] {}^{n}$

$( \frac{3}{5} ) {}^{60} = [( \frac{3 {}^{2} }{5 {}^{2} } ) {}^{5} ] {}^{n}$

$( \frac{3}{5} ) {}^{60} = [ (\frac{3}{5} ) {}^{10} ] {}^{n}$

$( \frac{3}{5} ) {}^{60} =( \frac{3}{5} ) {}^{10n} < = > 60 = 10n$

$10n = 60 \: = > \: n = \frac{60}{10} = 6$
