Question

dau coroana,urgent !
calculati respectand ordinea efectuarii operatiilor :
{[(1,44:2,4)+0,5²-0,3·0,8]:6,1} · 1000-9,1² =

Answer 1

1,44:2,4=
14,4:24=0,6
0,6+0,25-0,3•0,8=0,85-0,24=0,61
0,61:6,1=
6,1:61=0,1
0,1•1000=100
100-82,81=17,19
Sper ca nu am gresit la calcule

Answer 2

1.44/2.4=0.6
0.6+0.5*05=3.1
3.1-0.3*0.8=3.1-0.24=2.86
2.86/6.1=0.46
0.46*1000=468.85
468.85-9.1*9.1=386.04
