Cum se rezolva ? [tex] \sqrt\frac{1}{4} + \sqrt \frac{1}{9} + \sqrt \frac{49}{36} [/tex]

... = 1/2 + 1/3 + 7/6 =(3+2+7) / 6 = 2
[tex] \sqrt{ \frac{1}{4} } = \frac{1}{2} \\ \sqrt{ \frac{1}{9} } = \frac{1}{3} \\ \sqrt{ \frac{49}{36} } = \frac{7}{6} \\ Le~adunam: \\ \frac{1}{2}+\frac{1}{3} + \frac{7}{6}= \frac{3+2+7}{6} = \frac{12}{6} =2[/tex]
