Answer 1

$4 \sqrt{2 } + \sqrt{5 \times 5 \times 2} - \sqrt{3 \times 3 \times 2} = 4 \sqrt{2} + 5 \sqrt{2} - 3 \sqrt{2} = \sqrt{2} (4 + 5 - 3) = 6 \sqrt{2}$
$3 + \sqrt{12 \times 3} = 3 + \sqrt{3 \times 4 \times 3} = 3 + 3 \times 2 = 9$
$3 - 4 \sqrt{3} + 4 = 7 - 4 \sqrt{3}$
$7 + \sqrt{7} \times \sqrt{2} - \sqrt{2} \times \sqrt{7} - 2 = 5$
