a)[12.5-(0.3+1)²]*10²=[12,5-1,3*10²]=11.2*10²=11.2*100=1120
b) [(2-0.45:0.9)²+14.2]=[(2-0.5)²+14.2]=1.5²+14.2=3+14.2=17.2
c) [15:2-(4.7-10,8:4)²]:10=[7.5-(4.7-2.7)²]:10=7.5-2:10=5.5:10=0.55
d) [25:4+(3-0.54:0.6)²]=[6.25+(2.46+0.6)²]=6.25+3,06²=6,25+9.3636=15,6136
e)[(0.8*1.25+0.5)²+22:5]:10=[(1+0.5)²+4.4]:10=(2.25+4.4):10=6.65:10=0.665
f)[(0.08*7.5+0.7)²+14:...? imi spui cand faci poza clara!
