bonsoir quelqu'un peut m'aider c'est pour demain je n'y arrive pas du tout ces l'exercice 24 et 25​

bonjour

3 ⁴ x 3 ⁷ = 3 ¹¹

5 ³ x 5 = 5 ⁴

( - 2) ⁸ x ( - 2) ⁻⁵ = ( - 2) ³

10⁵/ 10 ³ = 10 ²

2 ¹/2⁸ = 2 ⁻⁷

9 ⁻³/9 ⁻³ = 9 ⁰ = 1

( 4²) ⁴ = 4 ⁸

( 3 ⁻²) ⁷ = 3 ⁻¹⁴

5⁴ x 3 ⁴ = 15 ⁴

2 ⁵ x 6 ⁵ = 12 ⁵

( 5/3)² = 25/9

( 1/x)⁵ = 1/x⁵

Bonsoir,

Exercice 24

a• 3^3 × 3^7 = 3^(3+7) = 3^10

b• 5^3 × 5 = 5^3 × 5^1 = 5^4

c• (-2)^8 × (-2)^(-5) = (-2)^3

d• 10^5/10^3 = 10^(5-3) = 10^2

e• 2^1/2^8 = 2^(-7)

f• 9^(-3)/9^(-3) = 9^0 = 1

g• (4²)⁴ = 4^(2×4) = 4^8

h• (3-²)^7 = 3-¹⁴

i• (10^-7)-² = 10¹⁴

Exercice 25

a• 5⁴ × 3⁴ = (5×3)⁴ = 15⁴

b• 2^5 × 6^5 = 12^5

c• (5/3)² = 5²/3² = 25/9

d• (1/x)^5 = 1/x^5
