Question

daca unui numar natural i se adauga cifra 0 si se aduna cu numarul initial se obtine suma 484 . Aflati nr dat .

Answer 1

notam numarul natural cu ,,x,,
adaugam lui ,,x,,pe ,,0,, si obtinem ,,x0,,=> x*10=x0

x0+x=484
x*10+x=484
10x+x=484
11x=484
x=484:11
x=44

x0+x=484....(44*10+44)
440+44=484
