$\bf \scriptsize{ \: \: 2 \sqrt{8} = 2 \sqrt{2^{2} \times 2} \: = \: 2 \times \sqrt{2^{2} } \times \sqrt{2} \: = \: 2 \times 2 \: \times \sqrt{2} } \\ \\ \bf \scriptsize{ = 4 \sqrt{2} }$

$\bf \scriptsize{Here, \: \: \: 4 \sqrt{2} - 2 \sqrt{8} + \frac{ \: \: 3}{ \sqrt{2} } \sqrt{2} } \\ \\ \bf \scriptsize{ = \sqrt{2} \: \: (4 - 4 + \frac{3}{2} )} \\ \\ \bf \scriptsize{ = \frac{3}{2} \sqrt{2} }$

Answer 2

Answer:

As the given Irrational numbers are not similar, so we reduce each irrational number in simplest form.

$\begin{gathered} \bf \scriptsize{ \: \: 2 \sqrt{8} = 2 \sqrt{2^{2} \times 2} \: = \: 2 \times \sqrt{2^{2} } \times \sqrt{2} \: = \: 2 \times 2 \: \times \sqrt{2} } \\ \\ \\ \bf \scriptsize{ = 4 \sqrt{2} }\end{gathered}</p><p>\bf \scriptsize{And \: \: \: \: \: \: \: \: \frac{ \: \: 3}{ \sqrt{6} } = \frac{ \: \: 3}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{3}{2} \sqrt{2} } \\ </p><p>\begin{gathered} \bf \scriptsize{Here, \: \: \: 4 \sqrt{2} - 2 \sqrt{8} + \frac{ \: \: 3}{ \sqrt{2} } \sqrt{2} } \\ \\ \\ \bf \scriptsize{ = \sqrt{2} \: \: (4 - 4 + \frac{3}{2} )} \\ \\ \\ \bf \scriptsize{ = \frac{3}{2} \sqrt{2} }\end{gathered}$
