Answer:

 \frac{3 +  \sqrt{2} }{4 +  \sqrt{2} }  \\  \rightarrow \:  \frac{3 +  \sqrt{2} }{4 +  \sqrt{2} }  \times   \frac{4 -  \sqrt{2} }{4 -  \sqrt{2} }  \\ \rightarrow \:     \frac{(3 +  \sqrt{2}) (4 -  \sqrt{2}) }{(4 +  \sqrt{2} )(4 -  \sqrt{2} )}   \\ \rightarrow \:  \frac{12 + 4 \sqrt{2} - 3 \sqrt{2}  - 2 }{ {(4)}^{2} -  { (\sqrt{2}) }^{2}  }  \\ \rightarrow \:  \frac{12  +  \sqrt{2}  - 2}{16 - 2}  \\ \rightarrow \:   \frac{10 +  \sqrt{2} }{14}
