c)18·4+29·17-75:3
d)400-6·6+2·8:4=

Answer 1

a)21:3+15:5=7+3=10

b)6000-12×3×4-9=6000-36×4-9=6000-144-9=5856-9=5847

c)18×4+29×17-75:3=72+493-25=565-25=540

d)400-6×6+2×8:4=400-36+16:4=400-36+4=436+4=440

Answer 2

Răspuns:

a) 21:3+15:5= b)6000-12•3•4-9= b)=5991

a) =7+3= b)=6000-12:4×3=

a) =10 b)=6000-3×3=

b)=600-9=

c) 18•4+29•17-75:3=

c)=18:4+29-17-25=

c)=4,5+29-17-25=

c)=33,5-17-29=

c)=16,5-29=

c)=-12,5

d)400-6•6+2•8:4=

d)=400-6×6+2×8:4=

d)=400-36+16:4=

d)=400-36+4=

d)=364+4=

d)=368

te rog frumos dă-mi coroana!!!
