Question

calcule as potências ​

Answer 1

$m) \: {( \frac{9}{6}) }^{2} = \frac{ {9}^{2} }{ {6}^{2} } = \frac{81}{36} = \frac{9}{4}$

$n) \: {( \frac{7}{4} )}^{ - 3} = \frac{ {4}^{3} }{ {7}^{3} } = \frac{64}{343}$

$o) \: {0.5}^{4} = {( \frac{5}{10}) }^{4} = {( \frac{1}{2}) }^{4} = \frac{ {1}^{4} }{ {2}^{4} } = \frac{1}{16}$

$p) \: {4.5}^{3} = {( \frac{45}{10}) }^{3} = {( \frac{9}{2}) }^{3} = \frac{ {9}^{3} }{ {2}^{3} } = \frac{729}{8}$
