Question

$(5 \sqrt{3} - 7 \sqrt{2}) \times (2 \sqrt{2} + 3 \sqrt{4})$
​

Answer 1

$= = > \: \: (5\sqrt{3} - 7 \sqrt{2} ) \times (2 \sqrt{2} + 3 \sqrt{4} ) \\ \\ = = > \: \: (5 \sqrt{3} - 7 \sqrt{2} ) \times (2 \sqrt{2} + 6) \\ \\ = = > \: \: 5 \sqrt{3} \times 2 \sqrt{2} + 5 \sqrt{3} \times 6 - 7 \sqrt{2} \times 2 \sqrt{2} - 7 \sqrt{2} \times 6 \\ \\ = = > \: \: 10 \sqrt{6} + 30 \sqrt{3} - 14 \times 2 - 42 \sqrt{2} \\ \\ = = > \: \: 10 \sqrt{6} + 30 \sqrt{3} - 28 - 42 \sqrt{2} \\ \\ = = > \: \: 10 \sqrt{6} + 30 \sqrt{3} - 42 \sqrt{2} - 28$
