Answer 2

Olá, Yasmimarques.

$a) \sqrt{2} * \sqrt{18} = \sqrt{2*18} = \sqrt{36} = 6 \\ b) \sqrt{5} * \sqrt{10} * \sqrt{2} = \sqrt{5*10*2} = \sqrt{100} = 10 \\ c) \sqrt{ \frac{3}{5} } * \sqrt{ \frac{5}{3} } = \sqrt{ \frac{3}{5} * \frac{5}{3} } = \sqrt{ \frac{15}{15}} = \sqrt{1} = 1 \\ d) ( \sqrt{9} ) = \sqrt{9} = 3 \\ e) \sqrt{6} / \sqrt{3} = \sqrt{2} \\ f) \sqrt{24} / \sqrt{3} = \sqrt{8} \\ g) \sqrt{3} * \sqrt{12} = \sqrt{3*12}= \sqrt{36} = 6$
$h) \sqrt{ \frac{3}{2}} / \sqrt{ \frac{1}{2} } = \sqrt{ \frac{3/1}{2/2}} = \sqrt{\frac{3}{1}} = \sqrt{3}$
