Question

Va rog mult ma puteti ajuta cu exercitile 8,9 .

Answer 1

Explicație pas cu pas:

ex 9

13-9+52+172=228

60-40+80+911=1011

630+20-11+10=650

9+11+40+57104=57164

1825+18-14+20=1849

Deocamdata acesta

(939-27+157):3+172=168:3+172=56+172=228

(240-160+320):4+911=400:4+911=100+911=1011

630+140:7=630+20=650

(81+99+360):9+57104=540:9+57104=57164

1825+(72-56+80):4=1825+96:4=1825+24=1849

ex 8

131-81+102=152

576-3680:4:4=576-920:4=576-230=346

1446-(750x3):5+75=1446-450+75=1071

1+1521=1522

(2209+200)x7:7=2409X7:7=16863:7=2409

896:2+380=448+380=828

[(10x42)-420]:9=(420-420):9=0:9=0+17=740

(602-21)+437=581+437=1018
