hey pouvez vous m’aidez svp c’est pour demain matin

Réponse :

C = 3×5^2+4

= 3×25+4

=75+4

=79

D = (3×5)^2+4

= 15^2+4

= 225+4

= 229

E = 3×( 5^2+4)

= 3×(25+4)

= 3×29

= 87

F = 3×(4+5)^2

= 3×9^2

= 3×81

= 243

C = 3 * 5² + 4

C = 3 * 5 * 5 + 4

C = 15 * 5 + 4

C = 75 + 4

C = 79

D = (3 * 5)² + 4

D = 15² + 4

D = 15 * 15 + 4

D = 225 + 4

D = 229

E = 3 * (5² + 4)

E = 3 * 5² + 3 * 4

E = 3 * 5 * 5 + 3 * 4

E = 15 * 5 + 3 * 4

E = 75 + 12

E = 87

F = 3 * (4 + 5)²

F = 3 * (9)²

F = 3 * 81

F = 243
