Calculati:

a.Calculati
136*25 - (324:2:9*3+41)+146-123:3

b.DETERMINATI VALOAREA LUI a

[48+50*100:(28:a+3*2)-14]*[(50-4*5)+(143-4*6)]= 42 316 

Answer 1

a) 3400-(162:27+41)+146-41
3400-(6+41)+105
3400-67+105
3333+105
3408
b) [48+5000:(28:a+6)-14]*[(50-20)+(143-24)]=42316
[48+5000:(28:a+6)-14]*(30+119)=42316
[48+5000:(28:a+6)-14]*149=42316
[48+5000:(28:a+6)-14]=42316:149
[48+5000:(28:a+6)-14]=284
48+5000:(28:a+6)=284+14
48+5000:(28:a+6)=298
5000:(28:a+6)=298-48
28:a+6=250-5000
28:a= -4750 -6
a= 4756 :28 = 344.5
