Question

\sqrt 1*49+ 1*16 (totul sub radical)
\sqrt 1*25-1*36 (totul sub radical)
rezolvarea o vreau

Answer 1

$\sqrt{\dfrac{1}{25}-\dfrac{1}{36}}$

Dupa ce aducem la acelasi numitor si efectuam scaderea fractiilor de sub radical, obtinem:

$\it\sqrt{\dfrac{11}{25\cdot36}}=\dfrac{\sqrt{11}}{5\cdot6}=\dfrac{\sqrt{11}}{30}$
