4)radical 28

5) 3 radical 2

6) radical 15

Answer 2

Răspuns:

$3) \sqrt{50} = \sqrt{5^{2} \times 2 } = 5 \sqrt{2} \\ 4)2 \sqrt{7} = \sqrt{ {2}^{2} \times 7} = \sqrt{4 \times 7 } = \sqrt{28} \\ 5)3 \sqrt{2} = \sqrt{ {3}^{2} \times 2} = \sqrt{18} \\ 2 \sqrt{3} = \sqrt{ {2}^{2} \times 3} = \sqrt{12} \\ \sqrt{18} > \sqrt{12} \\ 3 \sqrt{2} > 2 \sqrt{3} \\ 6) \sqrt{3} \times \sqrt{5} = \sqrt{3 \times 5} = \sqrt{15}$
