Răspuns:

Explicație pas cu pas:

a)

$\sqrt{3} *\sqrt{27} = \sqrt{3*27} = \sqrt{81} =\sqrt{9^2} = 9$

b)

$-\sqrt{2} *\sqrt{32} = -\sqrt{2*32} =- \sqrt{64} =-\sqrt{8^2} = -8$

c)

$\sqrt{18} *\sqrt{2} = \sqrt{18*2} = \sqrt{36} =\sqrt{6^2} = 6$

d)

$\sqrt{5} *|-\sqrt{45}| = \sqrt{5} *\sqrt{45}=\sqrt{5*45} = \sqrt{225} =\sqrt{15^2} = 15$
