Ce serait pour l’exercice 3 Merci

Bonjour,

A = 7⁴ × 7³ × 7 = 7⁴ × 7³ × 7¹ = 7⁴⁺³⁺¹ = 7⁸

B = 2⁵ × 8 = 2⁵ × 2³ = 2⁵⁺³ = 2⁸

C = 9 × 27 = 3² × 3³ = 3²⁺³ = 3⁵

D = 3² × 4² = (3×4)² = 12²

E = 25 × 0,2² = 5² × 0,2² = (5×0,2)² = 1² = 1

F = 1 000 × 10⁴ = 10³ × 10⁴ = 10³⁺⁴ = 10⁷

G = 10³ × 10³ × 10³ × 10³ = 10³⁺³⁺³⁺³ = 10¹²

I = 125 × 5² = 5³ × 5² = 5³⁺² = 5⁵

J = 3² × 9³ = 9 × 9³ = 9¹ × 9³ = 9¹⁺³ = 9⁴
