Ecuatiile acestea va rog ! Coronita !

Answer 1

$\\ g) \\ (3 \sqrt{3} + 2 \sqrt{2} ) {}^{2} = \\ 3 { \times 3}^{2} + 2 \times 2 \sqrt{2} \times 3 \sqrt{3} + 2 {}^{2} \times 2 = \\ 27 + 12 \sqrt{6} + 8 = 35 + 12 \sqrt{6}$

$h) \\ \\ (3 \sqrt{2} + 2 \sqrt{3} )(3 \sqrt{2} - 2 \sqrt{3} ) = 3 {}^{2} \times 2 - 2 {}^{2} \times 3 = 18 - 12 = 6$
