Pe o sarma stau 9 vrabii . Un vanator impusca o vrabie care cade jos . Cate vrabii mai sunt acum pe sarma ?

Nu mai ramane nicio vrabie, nu? Pentru ca vor zbura toate...

Pai nu am inteles ideea problemei . Trebuie sa scrii un patrat perfect care poate fi scris ca suma de doua patrate perfecte si sa le scrii pe acestea sau un patrat perfect care are suma cifrelor un patrat perfect ?





... ca , cine ... :)

Deci sti care sunt toate pp mai mici decat 100?
Scriele pe toatesi uita-te care adunate (cate 2) dau un alt patrat? De ex. 9 si 4= 13 nu e patrat perfect nu scrii...

Imi pare rau, dar trebuie sa zic ceva off topic...
Probleme de genul asta si ca si
" Pe gard sunt 10 pasari. Vanatorul impusca 2. Cate pasari mai sunt pe gard?"
nu sunt de matematica, fie ea si distractiva... Unul ar raspunde ca nu mai sunt pasari pe gard pentru ca s-au speriat, altul ar zice ca daca sunt bibelouri cumva (ca nu s-a zis nimic in ipoteza despre ele... ) atunci au mai ramas 8, si sunt nesfarsite variante...

Va las... :)

De asemenae am putea zice ca n-avea cum sa impuste 2 ca pana mai impusca una toate plec. :roll:

Nu m-am uitat prea atenta dar e chiar interesanta problema ta...
36 = \( 6^2 \).
3 + 6 = 9 = \( 3^2 \).

Imi pare rau ... eu m-am luat dupa modelul celorlalti . Pai tot asa n-ar avea nicio legatura cu matematica problemele cu pizza , problemele cu fratiorul Alin care minte sau vaporul care se ridica si totodata se ridica si scara cu el . :)


Aaa... si la problema lui Amaranth \( 9+16=25 \) sau \( 36+64=100 \)

Sau un exemplu ar mai fi , Amaranth , \( 81=9^2 \) cu \( 8+1=9=3^2 \)

Timbre

Post by Amaranth »

Andrei , Stefan si Vlad (A, S, V) au inceput sa colectioneze timbre... A are \( frac/{1}{3} \) din numarul timbrelor lui V, iar S are \( frac/{2}{3} \) din numarul timbrelor lui V, iar impreuna au 48 de timbre. Cate are fiecare? :lol:
