Exercice 76 :
↓
Enoncé :
Calculer les expressions suivantes :
\( 10^2 \times 4 - 3 \)
\( 3^4 + 5 \times 2 \)
\( 4^2 \times 6 + 9 \)
\( 2^5 - 7 \times 3 \)
↓
Solution :
\( 10^2 \times 4 - 3 = 100 \times 4 - 3 = 400 - 3 = 397 \)
\( 3^4 + 5 \times 2 = 81 + 10 = 91 \)
\( 4^2 \times 6 + 9 = 16 \times 6 + 9 = 96 + 9 = 105 \)
\( 2^5 - 7 \times 3 = 32 - 21 = 11 \)
