Răspuns:400·(102 + 532) = 400·634 =253600
8700÷(54·8)= 8700÷432=20,1388888889

Explicație pas cu pas:
400 × [(3 × 34)+532]=250.400
3 ×34=104
400 ×(104+532)=250.400
104+532=636
400 × 636=250.400
8700÷[54×(64:8)] =20,138888888888
64:8=8
8700÷(54×8)=20,138888888888
54×8=432
8700÷432=20,138888888888
540×(6×1)=3240
540×6=3240
