Witam.
[tex]a) \: \sqrt{2} \times \sqrt{8} = \sqrt{16} = 4[/tex]
[tex]b) \: \sqrt{3} \times \sqrt{12} = \sqrt{36} = 6[/tex]
[tex]c) \: \sqrt{5} \times \sqrt{20} = \sqrt{100} = 10[/tex]
[tex]d) \: \sqrt{2} \times \sqrt{32} = \sqrt{64} = 8[/tex]
[tex]e) \: \frac{ \sqrt{18} }{ \sqrt{2} } = \sqrt{ \frac{18}{2} } = \sqrt{9} = 3[/tex]
[tex]f) \: \frac{ \sqrt{12} }{ \sqrt{3} } = \sqrt{ \frac{12}{3} } = \sqrt{4} = 2[/tex]
[tex]g) \: \sqrt{45} \div \sqrt{5} = \frac{ \sqrt{45} }{ \sqrt{5} } = \sqrt{ \frac{45}{5} } = \sqrt{9} = 3[/tex]
[tex]h) \: \sqrt{75} \div \sqrt{3} = \frac{ \sqrt{75} }{ \sqrt{3} } = \sqrt{ \frac{75}{3} } = \sqrt{25} = 5[/tex]
