Răspuns:

${( \frac{3}{4}) }^{2} = \frac{ {3}^{2} }{ {4}^{2} } = \frac{9}{16} \\ \\ {( \frac{5}{3} )}^{2} = \frac{ {5}^{2} }{ {3}^{2} } = \frac{25}{9} \\ \\ {( \frac{4}{5} )}^{2} = \frac{ {4}^{2} }{ {5}^{2} } = \frac{16}{25} \\ \\ {( \frac{7}{3} )}^{2} = \frac{ {7}^{2} }{ {3}^{2} } = \frac{49}{9}$

${( \frac{2}{3} )}^{3} = \frac{ {2}^{3} }{ {3}^{3} } = \frac{8}{27} \\ \\ {( \frac{3}{4} })^{3} = \frac{ {3}^{3} }{ {4}^{3} } = \frac{27}{64} \\ \\ {( \frac{2}{3} })^{2} = \frac{ {2}^{2} }{ {3}^{2} } = \frac{4}{9}$

${( \frac{5}{3} )}^{3} = \frac{ {5}^{3} }{ {3}^{3} } = \frac{125}{27} \\ \\ {( \frac{1}{2}) }^{4} = \frac{1}{ {2}^{4} } = \frac{1}{16} \\ \\ {( \frac{2}{3} )}^{4} = \frac{ {2}^{4} }{ {3}^{4} } = \frac{16}{81}$

${( \frac{3}{2}) }^{4} = \frac{ {3}^{4} }{ {2}^{4} } = \frac{81}{16} \\ \\ {( \frac{4}{3} )}^{4} = \frac{ {4}^{ ^{4} } }{ {3}^{4} } = \frac{256}{81}$

Am utilizat formula:

${( \frac{a}{b} )}^{2} = \frac{ {a}^{2} }{ {b}^{2} }$
