Answer 1

$1. \: a) \: 2 \sqrt{12} = 2 \sqrt{4 \times 3} = 4 \sqrt{3} \\ b) \: \frac{1}{5} \sqrt{200} = \frac{1}{5} \sqrt{25 \times \: 8} = \sqrt{8} \\ c) \: \frac{ \sqrt{44} }{2} = \frac{ \sqrt{4 \times 11} }{2} = \sqrt{11}$

$2. \: a) \: \frac{1}{2} \sqrt{20} = \sqrt{ \frac{1}{4} \times 20} = \sqrt{5} \\ b) \: 6 \sqrt{2} = \sqrt{36 \times 2} = \sqrt{72} \\ c) \: - \frac{2}{3} \sqrt{45} = - \sqrt{ \frac{4}{9} \times 45} = \sqrt{20}$

$3. \: a) \: 2 \sqrt{5} = \sqrt{20} > 3 \sqrt{2} = \sqrt{18} \\ b) \: \sqrt{24} = \frac{1}{3} \sqrt{216} = \sqrt{24}$
