Question

Calculeaza,axb-c,stiind că:a=50+9:9-45 b=3x(300-55x5)x2+3-(14:7-5x0) c=35x2+45x3

Answer 1

Salutare!:)

a=50+9:9-45

a=50+1-45

a=51-45

a=6

b=3×(300-55×5)×2+3-(14:7-5×0)

b=3×(300-275)×2+3-(2-0)

b=3×25×2+3-2

b=75×2+3-2

b=150+3-2

b=153-2

b=151

c=35×2+45×3

c=70+135

c=205

Succes!
