Question

11 .Calculează a xb-c, știind că:
a = 50 +9:9-45 b = 3 x (300 - 55 x 5) x 2 +3 - (14:7-50)
c= 35 x 2 + 45 x 3​

Answer 1

Răspuns:

a= 50+9:9-45

a=50+1-45

a=51-45=6

b=3×(300-55×5)×2+3-(14:7-50)

b=3×25×2+3-(-48)

b=75×2+3-51

b=150+3-51

b=153-51

b=102

c=35×2+45×3=205

a×b-c=6×102-205=407
