    Answer:

     \frac{2  + \sqrt{2} }{2 -  \sqrt{2} }  =  \\  \\  =  >  \frac{(2 +  \sqrt{2)}(2 +  \sqrt{2} ) }{(2 -  \sqrt{2} )(2  +   \sqrt{2} ) }  \\  \\  \\  =  >  \frac{ {(2 +  \sqrt{2} )}^{2} }{4 - 2}  \\  \\  \\  \\  =  >  \frac{4 + 2 + 4  \sqrt{2}  }{2}  \\  \\  \\  =  >  \frac{6 + 4 \sqrt{2} }{2}  \\  \\  \\  \\  =  >  \frac{2(3 + 2 \sqrt{2}) }{2}  \\  \\  \\  =  > 3 + 2 \sqrt{2}  \\  \\  =  > 3 + 2 \times 1.41 \\  \\  \\  =  > 3 + 2.82 = 5.82
