Question

efectuati calculele respectand ordinea efectuarii operatiilor si desfacerea parantezelor exercitiul are patru subpuncte a b c d a este[3420:36-(5760:48-2880:36)];5 b =94+[(106*5003-4009*102):607-2]:33 c este[2560-48*(2304:48 -2208:92)]:64+8 sii d egal123- 5*{42:6+[7*(300:5-36:2)-60]:18} va rog

Answer 1

a)[3420:36-(5760:48-2880:36)]=
[3420:36-(120-80)]=
3420:36-40=
95-40=55

b)94+[(106x5003-4009x102):607-2]:33=
94+[(530318-408918):607-2]:33=
94+(121400:607-2):33=
94+(200-2):33=
94+198:33=
94+6=100

c)[2560-48x(2304:48-2208:92)]:64+8=
[2560-48x(48-24)]:64+8=
(2560-48x24):64+8=
(2560-1152):64+8=
1408:64+8=
22+8=30

d)123-5x{42:6+[7x(300:5-36:2)-60]:18}=
123-5x{42:6+[7x(60-18)-60]:18}=
123-5x[42:6+(7x42-60):18]=
123-5x[42:6+(294-60):18]=
123-5x(7+234:18)=
123-5x(7+13)=
123-5x20=
123-100=23
