Question

Помогите решить пожалуйста!

Answer 1

$1) \: \sqrt{200} - \sqrt{18} + \sqrt{50} = \sqrt{100 \times 2} - \sqrt{9 \times 2} + \sqrt{25 \times 2} = \\ \\ = 10 \sqrt{2} - 3 \sqrt{2} + 5 \sqrt{2} = 12 \sqrt{2}$

$2) \: \sqrt{12} + \sqrt{75} + \sqrt{48} = \sqrt{4 \times 3} + \sqrt{25 \times 3} + \sqrt{16 \times 3} = \\ \\ = 2 \sqrt{3} + 5 \sqrt{3} + 4 \sqrt{3} = 11 \sqrt{3}$
