Question

Rationalise1/3+√2 answer ​

Answer 1

Answer:

according to me the answer is

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

Step-by-step explanation:

given

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

multiplying numinator and denominator by

$3 - \sqrt{2}$

therefore

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

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

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

$= \frac{3 - \sqrt{2} }{9 - 2}$

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