Answer 1

2,4×10+59÷10-18÷2,5= 24+5,9-7,2=29,9-7,2=22,7
1,2la puterea2 +2,1la puterea2 -0,0017×1000=1,44+4,41-1,7=5,85-1,7=4,15
400÷200-1,73÷10+5,6×4,5=2-0,173+25,2=1,827+25,2=27,027
29÷100+3,7×4-123÷100=0,29+14,8-1,23=15,09-1,23=13,86
62÷10-0,02×10+28,5×2,2=6,2-0,2+62,7=6+62,7=68,7
3,9×100+3,9÷100-3,9la puterea2=390+0,039-15,21=390,039-15,21=374,829
