Question

Calculați : a) 2+1340:(164-60:2) =
b) 9-3•[9-3•(3-3:3)] =
c) [(289:17-2•5)•8+8] :8-1 =
d) 2000:{4+[2+(3+7:7)]} =

Va rog frumos dau coroana!​

Answer 1

A)2+1340:(164-60:2)=12
2+1340:(164-30)
2+1340:134
2+10=12
B)9-3x[9-3x(3-3x3)]=18
9-3x[9-3x(0x3)]
9-3x(9-3x0)=
9-3x(9-0)=
9-3x9
9-27=18
C)[(289:17-2x5)x8+8]:8-1=7
[(17-10)x8+8]:8-1
(7x8+8):8-1
(56+8):8-1
64:8-1
8-1=7
D)2000:{4+[2+(3+7:7)]}=200
2000:{4+[2+(3+1)]}
2000:[4+(2+4)]
2000:(4+6)
2000:10=200
