[tex][ \frac{1}{ \sqrt{3} - \sqrt{2}} ]\\[/tex]
Amplificam cu conjugata numitorului, rationalizand fractia:
[tex][ \frac{ \sqrt{3} + \sqrt{2} }{(\sqrt{3} - \sqrt{2} )(\sqrt{3} + \sqrt{2} )} ] =[ \frac{\sqrt{3} + \sqrt{2} }{3-2} ]=[ \sqrt{3} + \sqrt{2} ]\\[/tex]
Acum calculezi manual:
√3 ≈ 1.732
√2 ≈ 1.414
[tex][\sqrt{3} + \sqrt{2} ]=[1.73 + 1.41]=[3.14] = 3[/tex]
