Question

Efectuati calculele
$a) \: \: \sqrt{3} ( \sqrt{2} - 2\sqrt{5}) + \sqrt{60} - \sqrt{24} \\ b) \: \: 18( \sqrt{3} - 2 \sqrt{2} ) + 15(2 \sqrt{3} - 3 \sqrt{2} ) - 7( 3\sqrt{3} - \sqrt{2} ) \\ c) \: \: 5(4 \sqrt{3} - 3 \sqrt{5} ) - 7(2 \sqrt{3} + 4 \sqrt{5} ) + 2(3 \sqrt{3} + 6 \sqrt{5} ) \\ d) \: \: 16 \sqrt{7} - 4(2 \sqrt{3} - 3 \sqrt{7} ) + 8( \sqrt{7} - 3 \sqrt{3} ) \\ e) \: \: (18 \sqrt{2} - 24 \sqrt{3} ) \div 6 + 2(4 \sqrt{3 } - 3 \sqrt{2} ) - (30 \sqrt{3} + 15 \sqrt{2} ) \div 5 \\ f) \: \: \sqrt{3} (4 + \sqrt{6} ) - ( \sqrt{12} - \sqrt{18} ) + ( \sqrt{27} + 2 \sqrt{6} ) \div \sqrt{3} - ( \sqrt{8} + 3) \\ g) \: \: ( \sqrt{50} - 3 \sqrt{10} ) \div \sqrt{2} - ( \sqrt{45} - 5) + \sqrt{75} \\ h) \: \: ( \sqrt{54} - \sqrt{24} ) \div \sqrt{3} - ( \sqrt{160} - \sqrt{40} ) \div \sqrt{5} \\ i) \: \: ( \sqrt{240}- \sqrt{60} ) \div \sqrt{3} - ( \sqrt{250} + \sqrt{360} ) \div \sqrt{2}$
