Va rog sa ma ajutati la aceste trei exercitii!!!

Answer 1

[(102x14+42x20-1968):100+(13452:38+95x10+2696):1000]:7 =
=[(1428+840-1968):100+(354+950+2696):1000]:7 =
=(300:100+4000:1000):7 =
=(3+4):7 =
=7:7=1


[121-80:(1596:57+4992:96)-20:(1750:25-3000:60)]-119=
=[121-80:(28+52)-20:(70-50)]-119=
=(121-80:80-20:20)-119=
=(121-1-1)-119=
=119:119=1

6000-[(48x16+36x18+69):45+(1105:85+97x35)]=
=6000-[(768+648+69):45+(13+3395)]=
=6000-(1485:45+3408)=
=6000-(33+3408)=
=6000-3441=
=2559
