Bonjour
5^4 - 5^2 = 5^2(5^2 - 1) = 25(25 - 1) = 25 x 24 = 600
V100 = V(10 x 10) = V(10^2) = 10
(-6)^2 = 6^2 = 6 x 6 = 36
V(-9) => pas de solution une racine carrée est toujours positive
(3/5)^2 = 3^2/5^2 = 9/25
Racine cubique (-125) = Racine cubique(-5 x (-5) x (-5)) = -5
10^(-2) = 1/10^2 = 1/(10 x 10) = 1/100 = 0,01
10^6 x 10^(-3) = 10^(6-3) = 10^3
