Metoda 1. Se aproximeaza valoarea numarului a.
a≈1,41+1,73=3,14. => [a]=3.
Metoda 2. Se incadreaza intre doua numere intregi consecutive.
[tex] 1,3\ \textless \ \sqrt{2} \ \textless \ 2 \\ 1,7\ \textless \ \sqrt{3}\ \textless \ 2 \\ 3\ \textless \ \sqrt{2}+ \sqrt{3}\ \textless \ 4\ \textless \ =\ \textgreater \ 3\ \textless \ a\ \textless \ 4=\ \textgreater \ [a]=3. [/tex]
