Answer 2

Question :-

$\frac{1 + \sqrt{2} }{3 - 2 \sqrt{2} }$

What to do = rationalisation?

Solution :-

We know that :-

Rationalisation Factor is =

$(3 + 2 \sqrt{2} )$

Hence,

$( \frac{1 + \sqrt{2} }{3 - 2 \sqrt{2} } ) \times ( \frac{3 + 2 \sqrt{2} }{3 + 2 \sqrt{2} } )$

Now solve this

$( \frac{3 + 2 \sqrt{2} + 2 \sqrt{2} + 2 \times 2 }{9 - 8} ) \\ \\ = (7 + 4 \sqrt{2} ) = 7 + 4 \times 1.414 \\ \\ = 12.65 \: \: \: \: ans$
