Answer 1

Poza contine rezolvarea

Answer 2

$a = ( \sqrt{3} + \sqrt{2} ) \times (5 - \sqrt{6} ) + {( \sqrt{2} - 1) }^{2} - 3 \sqrt{3}$

$a = 5 \sqrt{3} - \sqrt{18} + 5 \sqrt{2} - \sqrt{12} + 2 - 2 \sqrt{2} + 1 - 3 \sqrt{3}$

$a = 5 \sqrt{3} - 3\sqrt{2} + 5 \sqrt{2} - 2 \sqrt{3} +2 - 2\sqrt{2} + 1 - 3 \sqrt{3}$

( se reduc numerele de sub radical)

$a = 2 + 1$

$a = 3$
