{100+7+[300-5 x (2730-25-108)]}

Ajutati-ma si cu:
a.64+{3+5 x [29+2 x(4831-30 x 166)]}
b.6225-2 x{ 5 x [2 x(107 + 13)+3 x (104+8)]}

Answer 1

1){100+7+[300-5*(2730-25-108)]}=[107+(300-5*2597)]=(107+300-12985)=-12578
2)64+{3+5*[29+2*(4831-30*166)]}=64+{3+5[29+2(4831-4980)]}=64+{3+5[29+2*(-149)]}=64+[3+5(29-298)]=64+[3+5*269]=64+3+1345=1412
3)6225-2*{5*[2*(107+13)+3*(104+8)]}=6225-2{5[2)107+13)+3(104+8)=6225-2[5(2*94+3*96)]=6225-2[5(188+288)]=6225-2(5*476)=6225=2*2380=6225-4760=1465
