Explicație pas cu pas:
a)
[tex] {3}^{4} = 81[/tex]
b)
[tex] \frac{1}{32} = \frac{1}{ {2}^{5} } = {2}^{ - 5} [/tex]
c)
[tex]\frac{1}{25} = \frac{1}{ {5}^{2} } = {\Big( \frac{1}{5} \Big)}^{2} [/tex]
d)
[tex]64 = {4}^{3} = \frac{1}{ {4}^{ - 3} } = {\Big( \frac{1}{4} \Big)}^{ - 3} [/tex]
e)
[tex] \frac{8}{27} = \frac{ {2}^{3} }{ {3}^{3} } = {\Big( \frac{2}{3} \Big)}^{3} [/tex]
f)
[tex] \frac{25}{16} = \frac{ {5}^{2} }{ {4}^{2} } = {\Big( \frac{5}{4} \Big)}^{2} = {\Big( \frac{4}{5} \Big)}^{ - 2} [/tex]
