nimic dificil

Answer 2

[tex] a)(\frac{1}{2}^{7}= \frac{1^{7}}{2^{7}}= \frac{1}{128} \\ \\b)(\frac{2}{3})^{5}= \frac{2^{5}}{3^{5}}= \frac{32}{243} \\ [/tex]

[tex]c)(\frac{4}{9}^{3}= \frac{4^{3}}{9^{3}}= \frac{64}{729} \\ \\d)(\frac{11}{7})^{3}= \frac{11^{3}}{7^{3}}= \frac{1331}{343} [/tex]

[tex]e)(\frac{5}{4})^{4}= \frac{5^{4}}{4^{4}}= \frac{625}{256} \\ \\f)(\frac{3}{3})^{2017}= {1^{2007}}= 1 [/tex]

$g)(\frac{19}{43})^{1}=\frac{19}{43}$

$h)(\frac{2011}{2017})^{0}=1$
