Explicație pas cu pas:
a)
[tex] \frac{1}{ {2}^{4} } = \frac{1}{16} [/tex]
b)
[tex] \frac{1}{10} [/tex]
c)
[tex] \frac{1}{ {7}^{2} } = \frac{1}{49} [/tex]
d)
[tex] - \frac{1}{ {5}^{3} } = - \frac{1}{125} [/tex]
e)
[tex] \frac{1}{ { (\frac{2}{5}) }^{2} } = \frac{1}{ \frac{4}{25} } = \frac{25}{4} [/tex]
f)
[tex] \frac{1}{ {( \frac{1}{ \sqrt{3} } )}^{4} } = \frac{1}{ \frac{1}{ { \sqrt{3} }^{4} } } = \frac{1}{ \frac{1}{9} } = 9[/tex]
g)
[tex] { (\frac{5}{3} )}^{ - 2} = \frac{1}{ {( \frac{5}{3} )}^{2} } = \frac{1}{ \frac{25}{9} } = \frac{9}{25} [/tex]
h)
[tex] - { (\frac{16}{7} )}^{ - 1} = - \frac{7}{16} [/tex]
