Question

fara a calcula radacina patrata incadrati urmatorii radicali intre doua numere naturale consecutive: radical 8, radical 17, radical 28, radical 101, radical 180. Nu inteleg cum se face. Adica spre exp. la radical din 8 e 7 si 9 sau 3 si 5

Answer 1

Răspuns:

Explicație pas cu pas:

$\sqrt{4}<\sqrt{8}<\sqrt{9},~deci~2<\sqrt{8}<3\\ \sqrt{16} <\sqrt{17}<\sqrt{25},~deci~4<\sqrt{17}<5\\ \sqrt{25}<\sqrt{28}<\sqrt{36},~deci~5<\sqrt{28}<6\\ \sqrt{100}<\sqrt{101}<\sqrt{121},~deci~10<\sqrt{101}<11\\ \sqrt{169}<\sqrt{180}<\sqrt{196},~deci ~ 13<\sqrt{180}<14$
