Exercice 74 :
↓
Enoncé :
Calculer les expressions suivantes :
\( 2^3 \times 5 - 3 \)
\( 3^2 \times 4 + 7 \)
\( 5^2 \times 2 - 6 \)
\( 4^3 - 5 \times 2 \)
↓
Solution :
\( 2^3 \times 5 - 3 = 8 \times 5 - 3 = 40 - 3 = 37 \)
\( 3^2 \times 4 + 7 = 9 \times 4 + 7 = 36 + 7 = 43 \)
\( 5^2 \times 2 - 6 = 25 \times 2 - 6 = 50 - 6 = 44 \)
\( 4^3 - 5 \times 2 = 64 - 10 = 54 \)
