Answer 1

$( \sqrt{20} - \sqrt{5} ) \times \sqrt{5} = (2 \sqrt{5} - \sqrt{5} ) \sqrt{5} = \sqrt{5} \sqrt{5} = 5$

$( \sqrt{18} - \sqrt{2} ) \times \sqrt{2} = (3 \sqrt{2} - \sqrt{2} ) \sqrt{2} = 2 \sqrt{2} \sqrt{2} = 2 \times 2 = 4$

$( \sqrt{48} - \sqrt{3} ) \times \sqrt{3} = ((4 \sqrt{3} - \sqrt{3} ) \sqrt{3} = 3 \sqrt{3} \sqrt{3} = 3 \times 3 = 9$

$( \sqrt{50} + \sqrt{2} ) \times \sqrt{2} = (5 \sqrt{2} + \sqrt{2} ) \sqrt{2} = 6 \sqrt{2} \sqrt{2} = 6 \times 2 = 12$

$( \sqrt{45} + \sqrt{5} ) \times \sqrt{5} = (3 \sqrt{5} + \sqrt{5} ) \sqrt{5} = 4 \sqrt{5} \sqrt{5} = 4 \times 5 = 20$

$( \sqrt{27} + \sqrt{3} ) \times \sqrt{3} = (3 \sqrt{3} + \sqrt{3} ) \sqrt{3} = 4 \sqrt{3} \sqrt{3} = 4 \times 3 = 12$
