bonjour

a) 4 ³ x 5 ³ =  ( 4 x 5 ) ³ = 20 ³

b)  ( 7 x 6) ⁴ = 7 ⁴ x 6 ⁴  = 42 ⁴

Explications étape par étape

Bonjour,

a. 4³ × 5³ = 8 000

4³ × 5³ = (4 × 5)³ c'est à dire 4³ × 5³ = 20³

4³ × 5³ = 8 000

b. (7 × 6)⁴ = (7 × 6) × (7 × 6) × (7 × 6) × (7 × 6)

(7 × 6)⁴ = 42⁴ = 3 111 696

(7 × 6)⁴ = 7⁴ × 6⁴
