Question

5*7²-3²*{2²*3³-2*[2³*3²-5*(3⁴-5²*3)]}

Answer 1

faci pur si simplu riicarile la puteri si apoi devine o ecuatie pe care ai invatat-o inca din clasa a 2-a
5*7²-3²*{2²*3³-2*[2³*3²-5*(3⁴-5²*3)]} 
5*49-9*{4*27-2*[8*9-5(81-25*3)]}
245-9{108-2*[72-5(81-75)]}
245-9[108-2*(72-5*6)]
245-9[108-2*(72-30)]
245-9(108-2*42)=
245-9(108-84)=
245-9*24=
245-216=
29

Answer 2

5*7²-3²*{2²*3³-2*[2³*3²-5(3⁴-5²*3)]}=
5*49-9*{4*27-2[8*9-5(81-25*3)]}=
5*49-9{108-2[8*9-5(81-75)]}=
5*49-9108-2[8*9-5*(6)]}=
5*49-9[108-2(8*9-5*6)]=
5*49-9[108-2(72-30)]=
5*49-9[108-2(42)]=
5*49-9(108-84)=
5*49-9*24==
245-216=29
