Question

Rationalise the denominater 3+√2

Answer 1

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

$\frac{3 - \sqrt{2} }{ {3}^{2} - {( \sqrt{2} })^{2} }$

$\frac{3 - \sqrt{2} }{7}$

Answer 2

Answer:

For rationalization we multiply and divide 3+√2 with its conjugate (3-√2).

Step-by-step explanation:-

Now,

      =1/ (3+√2 ) * (3-√2 )/(3-√2 )

      = (3-√2)/(9-2)

      =(3-√2)/7
