Answer 2

Răspuns:

a) 5×[100-6×(60-15×3)]=5×[100-6×(60-45)]=5×(100-6×15)=5×(100-90)=5×10=50

b) 4×[10×(21×5-85)-93]=4×[10×(105-85)-93]=4×(10×20-93)=4×(200-93)=4×107=428

c) [90+8×(16×3-32)]×17=[90+8×(48-32)]×17=(90+8×16)×17=(90+128)×17=218×17=3706

d) 8×[25×(78-19×4)-35]=8×[25×(78-76)-35]=8×(25×2-35)=8×(50-35)=8×15=120
