Je n’arrive pas à faire cette exercice prouver-vous m’aider merci(c’est le 25 )

Bonjour,

10⁻³ = 1/10³ = 1/1000 = 0,001

(-3)⁻⁴ = 1/(-3)⁴ = 1/81

7⁻² = 1/7² = 1/49

-3⁻² = -1/3² = -1/9

5⁻¹ = 1/5¹ = 1/5 = 0,2

2⁻⁴ = 1/2⁴ = 1/16 = 0,0625

(3/2)⁻² = 1/(3/2)² = 1/(9/4) = 4/9

(2/5)⁻¹ = 1/(2/5) = 5/2 = 2,5

(4/3)⁻³ = 1/(4/3)³ = 1/(64/27) = 27/64 = 0,421875
