Bonjour, j'ai un exercice de mathématiques de niveau 4ème.
"Pour les exercices 34 et 35, écrire à l'aide d'une seule puissance de 10"
34) a.10(exposant3)x10(exposant5)
b.10(exposant4)x10(exposant-7
c.10(exposant-4)x10(exposant-6
35) a. (10(exposant3))exposant4
b. (10(exposant-2))exposant5
c. (10(expo-6)expo-3
Je ne peux pas écrire les exposant en chiffres, c'est pourquoi ils sont en lettres.
Merci de votre aide

Bonjour
a) 10 ³ x 10 ⁵ = 10 ⁸
b) 10 ⁴ x 10 ⁻⁷ = 10 ⁻³
c) 10 ⁻⁴ x 10 ⁻⁶ = 10 ⁻¹⁰
a) (10³)⁴ = 10 ¹²
b) (10⁻²)⁵ = 10 ⁻¹⁰
c) (10⁻⁶)⁻³ = 10 ¹⁸

Bonjour voilà la réponse :
Exo 34
a. 10^3 x 10^5 = 10^3+5 = 10^8
b. 10^4 x 10^-7 = 10^4+(-7) = 10^4-7 = 10^-3
c. 10^-4 x 10^-6 = 10^-4+(-6) = 10^-10
Exo 35
a. (10^3)^4 = 10^3x4 = 10^12
b. (10^-2)^5 = 10^-2x5 = 10^-10
c. (10^-6)^-3 = 10^-6x(-3) = 10^18
Voilà j'espère avoir pu t'aider ^^
