Bună! ❤️

Răspuns:

$a) \sqrt{2 } \times ( \sqrt{2} + \sqrt{3} ) - \sqrt{3} \times ( \sqrt{2} + \sqrt{ 3} = \\ \\ \sqrt{4} + \sqrt{6} - \sqrt{6} + \sqrt{9} = \\ \\ 2 + \sqrt{6} - \sqrt{6} + 3 = \\ \\ 2 + 0 + 3 = 5$

$c)3 \sqrt{2} \times (3 \sqrt{2} + \sqrt{3} ) - \sqrt{3} \times (3 \sqrt{2} + \sqrt{3} ) = \\ \\ 9 \sqrt{4} + 3 \sqrt{6} - 3 \sqrt{6 } - \sqrt{9} = \\ \\ 18 - 3 = 15$

Succes ❗
