• Calculons.

[tex]\boxed{\boxed{8^{2}=8\times 8=\blue{64}}}[/tex]

[tex]\boxed{\boxed{(-5)^{3}=-5\times (-5)\times (-5)=\blue{-125}}}[/tex]

[tex]\boxed{\boxed{2^{-4}=\frac{1}{2\times 2\times 2\times 2} =\frac{1}{16}=\blue{0,0625 }}}[/tex]

[tex]\boxed{\boxed{5^{-2}=\frac{1}{5\times 5}=\frac{1}{25}=\blue{0,04}}}[/tex]

Réponse:

[tex]{8}^{2} = 8 \times 8 = 64 [/tex]

[tex] {( - 5)}^{3} = ( - 5) \times ( - 5) \times ( - 5) = - 125[/tex]

[tex] {2}^{ - 4} = \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{16} [/tex]

[tex] {5}^{ - 2} = \frac{1}{5} \times \frac{1}{5} = \frac{1}{25} [/tex]
