Odpowiedź:
D.
Szczegółowe wyjaśnienie:
A.
[tex] \sqrt{2} \times \sqrt{6} = \sqrt{2 \times 6} = \sqrt{12} [/tex]
B.
[tex] \frac{ \sqrt{60} }{ \sqrt{5 } } = \sqrt{ \frac{60}{5} } = \sqrt{ \frac{12}{1} } = \sqrt{12} [/tex]
C.
[tex]2 \sqrt{2} \times \sqrt{3} = \sqrt{8} \times \sqrt{3 } = \sqrt{8 \times 3} = \sqrt{24} [/tex]
D.
[tex]3 \sqrt{2} \times \sqrt{8} = \sqrt{18} \times \sqrt{8} = \sqrt{18 \times 8} = \sqrt{144} [/tex]
144 | 2
72 | 2
36 | 2

2*2*3 = 12
[tex] \sqrt{144} = 12[/tex]
