Question

a=28+{08-3•[(10+3•5):5]-4•}si b=3+5•{2+5•[2+5•(2+5•2)-2}-2
va rog frumos sa ma ajutati la problema aceasta ​ ca nu stiu stau la ia de o oră !

Answer 1

Răspuns:

A=28+{08-3•[(10+3•5):5]-4}=

28+{08-3•[(10+15):5]-4}=

28+[08-3•(25:5)-4]=

28+(08-3•5-4)=

28+(08-15-4)=

28+(7-4)=

28+3=31

A=31

B=3+5•{2+5•[2+5•(2+5•2)-2]-2}=

3+5•{2+5•[2+5•(2+10)-2]-2}=

3+5•[2+5•(2+5•12)-2]-2=

3+5•[2+5•(2+5•12)-2]-2=

3+5•[2+5•(2+60)-2]-2=

3+5•(2+5•62-2)-2=

3+5•(2+310-2)-2=

3+5•(312-2)-2=

3+5•310-2=

3+1550-2=

1553-2=1551

B=1551

A<B
