[tex] \frac{ \sqrt{50 \times 11} }{ \sqrt{11} } = \frac{ \sqrt{50} \times \sqrt{11} }{ \sqrt{11} } = \sqrt{50} \\ = \sqrt{5 \times 5 \times 2} = \sqrt{5 \times 5} \times \sqrt{2} \\ = 5 \sqrt{2} [/tex]
[tex] \sqrt{34} \times \sqrt{8} \\ = \sqrt{17 \times 2} \times \sqrt{2 \times 2 \times 2} \\ = \sqrt{17} \times \sqrt{2} \times \sqrt{2} \times \sqrt{2 \times 2} \\ = \sqrt{17} \times 2 \times 2 = 4 \sqrt{17} [/tex]
