Scuzați-mă ca este întoarsa pora. Va rog ajutați-mă la ex 4 !!! Daucoroniță! Repede va rog!

Answer 1

a)3+3*[3+3:3*(3+3*3)]:15=3+3*[3+3:3*(3+9)]:15=3+3*[3+3:3*12]:15=3+3*(3+1*12):15=3+3*(3+12):15=3+3*15:15=3+45:15=3+3=6

b)812-4*[6*(61-3600:12:30)]:9=812-4*[6*(61-300:30)]:9=812-4*(6*51):9=812-4*306:9=812-1224:9=812-136=676

c)[214+240:(16-2*5)]*25-25:25=[214+240:(16-10)]*25-25:25=[214+240:6]*25-25:25=(214+40)*25-25:25=254*25-25:25=6359-25:25=6350-1=6349....d)...e)...f) daca nu te descurci le rezolv si pe restul

d)90+7*[1614-12000:(18-10)]-16=90+7*[1614-12000:(18-10)]-16=90+7*[1614-12000:8]-16=90+7*(1614-1500)-16=90+7*114-16=90+798-16=888-16=872

e)44+8*[280:(37-1480:29:37)]:32-7=44+8*[280:(37-74:37)]:32-7=44+8*[280:(37-2)]:32-7=44+8*(280:35):32-7=44+8*8:32-7=44+64:32-7=44+2-7=46-7=35


f)(18*8+56):[50*40:(220-2*60)]=(144+56):[50*40:(220-120)=200:[50*40:100]=200:(2000:100)=200:20=10
le am facut pe toate ok
