Answer 1

The answer is

$\frac{9 \sqrt{2} }{2}$

Answer 2

Answer:

$\frac{9}{ \sqrt{2} }$

Step-by-step explanation:

$\frac{4}{ \sqrt{2} } - \frac{6}{ \sqrt{8} } + 4 \sqrt{18} - 8 \sqrt{2} \\ 2 \sqrt{2} - \frac{3 \sqrt{2} }{2} + 12 \sqrt{2} - 8 \sqrt{2} \\ = \frac{(4 - 3 + 24 - 16) \sqrt{2} }{2} \\ = \frac{9 \sqrt{2} }{2} \\ \ = \frac{9}{ \sqrt{2} }$
