Question

determinati ordinea efectuarii operatiilor:
16·0,02+2,5²:10=
35,7:100+1,4³·10=
6,5·{14,3-8,4}+7,2³=
{12,81-3,06}²-147,5:10=
cu operatii va rog mult ajutatima dau coroana si un multumesc si 5 stele ajutor va rog

Answer 1

1.16*0,02+2,5la patr=6.27(i operatie inmultirea, a doua ridicarea la patrat si a 3-a adunarea)
2.37,5:100+1,4 la a treia*10=
0.375+(14/10)la puterea3*10=
0,375+(7/5) la puretea3=
0,375+343/125*10=
0,375+343/25*2=
0,375+686/25=
0,375+27,44=
27,815-
3.6,5*{14,3-8,4} +7,2 la puterea3=
6,5*5,9(72/10) la puterea3=
38.35+(36/5) la puterea 3 =
3835/100+46656/125=
19175+186624/500=
205799/500=
411,598
4. {12,81-3,06} la puterea2- 147,5:10=
9,75 la a2-14,75=
(975/100) la a2 -1475/100
(39/4) la a2-59/4=
1521/16-59/4=
(1521-236)/16
1285/16
