Answer 2

Răspuns:

Buna

a)

$( \sqrt{2} + 1) \times ( \sqrt{2} + 2) \times ( \sqrt{2} + 3)$

$(2 + 2 \sqrt{2} + \sqrt[]{2} + 2) \times ( \sqrt{2}+ 3)$

$(4 + 3 \sqrt{2} )\times ( \sqrt{2} + 3)$

$4 \sqrt{2} + 12 + 6 + 9 \sqrt{2}$

$13 \sqrt{2 } + 18$

b)

$(2 \sqrt{2} - \sqrt{3}) \times (2 \sqrt{2} + \sqrt{3} ) \times ( \sqrt{3} - \sqrt{2})$

$(4 \times 2 - 3) \times( \sqrt{3} - \sqrt{2} )$

$(8 - 3) \times ( \sqrt{3} - \sqrt{2})$

$5( \sqrt{3} - \sqrt{2})$

$5 \sqrt{3} - 5 \sqrt{2}$
