Answer 1

Răspuns:

$\sqrt{3} - \sqrt{2}$

Explicație pas cu pas:

$(\frac{2}{\sqrt{2} } - \frac{3}{\sqrt{3} } )*\sqrt{6} + (\frac{3}{\sqrt{18} } - \frac{10}{\sqrt{75} } )(-\sqrt{6} )$  

$= (\frac{2\sqrt{3} - 3\sqrt{2} }{\sqrt{6} } )*\sqrt{6} + (\frac{3}{3\sqrt{2} } - \frac{10}{5\sqrt{3} } )(-\sqrt{6} )$

$= 2\sqrt{3} - 3\sqrt{2} +( \frac{1}{\sqrt{2} } - \frac{2}{\sqrt{3} } )(-\sqrt{6} )$

$= 2\sqrt{3} - 3\sqrt{2} + \frac{\sqrt{3} - 2\sqrt{2} }{\sqrt{6} } (-\sqrt{6} )$

$= 2\sqrt{3} - 3\sqrt{2} - \sqrt{3} + 2\sqrt{2}$

$= \sqrt{3} - \sqrt{2}$
