Exo 2

18^3=16^3+12^3 Faux

6^3=4^3+2^3. Faux

6×6×6=216

(4×4×4)+(2×2×2)=72

Bonne soirée ☺

A = 3³ + 2³

A = 3×3×3+×2×2×2

A = 27 + 8

A = 35

B = (3+5)²

B = 8²

B = 8×8

B = 64

C = 3 + 5²

C = 3 + 25 car 5 × 5 = 25

C = 28

D = 4³ × 4¹

D = 4×4×4×4

D = 256

ex 2 ✅

18⁴ = 104 976 et 16⁴ + 12⁴ = 86272

donc 18⁴ ≠ 16⁴ + 12 ⁴

donc faux

6³ = 216

et 4³ + 2³ = 72

donc faux
