Question

Calculati:

a) (−3)[(−24):(+3)+(−72):(+8)−(−15):(+3)]=

b) (−2)[(−8)(+9)+(−6)(−13)]+(−49+65)=

c) |230−320|+|230+320|−2∙320=

d) [0,2(7)+0,(27)]:0,5=

e) 123:0,(6)−0,5=

dau coroana la primul care raspunde

Answer 1

a) (-3)×(-8)+(-9)-(-5)=24-9+5=15+5=20

b) (-2)×[(-72)+78]+16=(-2)×6+16=-12+16=4

c) |-90|+|550|-640=90+550-640=640-640=0

Imi pare rau, dar nu mai am timp sa rezolv in acest moment ultimele 2 subpuncte, dar sper ca te-am ajutat la celelalte:)
