Va rog mult este urgent i),j),K) și L)

Answer 1

Salut!

$i) ( ( \frac{2}{3} ) {}^{3} ) {}^{6} \\ = > ( \frac{2}{3} ) {}^{18} \\ = > \frac{2 {}^{18} }{3{}^{18} }$

$k) ( \frac{9}{5} ) {}^{15} \div ( \frac{7}{5}) {}^{15} \\ ( \frac{9}{5} \div \frac{7}{5} ) {}^{15} \\ = > ( \frac{9}{5} \times \frac{5}{7} ) {}^{15} \\ = > (\frac{9}{7} ) {}^{15}$

$j) ( \frac{2}{3}) {}^{5} \times ( \frac{3}{7}) {}^{5} \\ ( \frac{2}{3} \times \frac{3}{7} ) {}^{5} \\ (2 \times \frac{1}{7} ) {}^{5} \\ = > ( \frac{2}{7} ) {}^{5} \\ = > \frac{32}{16807}$

$l) ( \frac{8}{26} ) {}^{3} \div ( \frac{4}{13} ) {}^{3} \\ ( \frac{8}{26} \div \frac{4}{13} ) {}^{3} \\ ( \frac{8}{26} \times \frac{4}{13} ) {}^{3} \\ ( \frac{2}{2} ) {}^{3} \\ = > 1 {}^{3} \\ = > 1$

Sper ca ți-am fost de ajutor=)

Succes la școală!
