bonjour

tu as vu en cours que

a⁻ⁿ = 1/a

tu appliques

A = 1/2⁵

B = 1/5

C = 1/4³

D = 1/0,1²

E = 1/(-3)⁴ = 1/3⁴

F = -1/3⁴

G = -1/1,1³

et H = -20x(-20) = +400

Bonjour,

Réponse :

[tex]2^{-5}=\frac{1}{2^5}=\boxed{\frac{1}{32} }[/tex]

[tex]5^{-1} = \frac{1}{5^1} =\boxed{\frac{1}{5} }[/tex]

[tex]4^{-3} = \frac{1}{4^3} =\boxed{\frac{1}{64} }[/tex]

[tex]0,1^{-2} = \frac{1}{0,1^2} =\frac{1}{0,01}=\boxed{100}[/tex]

[tex](-3)^{-4}=\frac{1}{(-3)^4}= \boxed{\frac{1}{81} }[/tex]

[tex]-3^{-4}=-\frac{1}{3^4}= \boxed{-\frac{1}{81} }[/tex]

[tex]-1,1^{-3}= -\frac{1}{1,1^3} =-\frac{1}{1,331} =\boxed{-\frac{1000}{1331} }[/tex]

[tex](-20)^2=20^2=\boxed{400}[/tex]

En espérant t'avoir aidé, bonne continuation ! :)
