Step-by-step explanation:

when we have to Symmetry

the equation,

it is very important to change sign.

Answer 2

Given,

$: \implies\frac{4 + \sqrt{2} }{3 \sqrt{2} }$

To Find,

The Rationalize Form of ;

$\frac{4 + \sqrt{2} }{3 + \sqrt{2} }$

Solution,

$: \implies \frac{4 + \sqrt{2} }{3 + \sqrt{2} } \\ \\ : \implies \frac{4 + \sqrt{2} }{3 + \sqrt{2} } \times \frac{3 - \sqrt{2} }{3 - \sqrt{2} } \\ \\ : \implies \frac{(4 + \sqrt{2} )(3 - \sqrt{2}) }{(3 + \sqrt{2})(3 - \sqrt{2} )} \\ \\ : \implies \frac{4(3 - \sqrt{2}) + \sqrt{2} (3 - \sqrt{2}) }{ {3}^{2} - {( \sqrt{2} )}^{2} } \\ \\ : \implies \frac{12 - 4 \sqrt{2} + 3 \sqrt{2} - 2}{9 - 2} \\ \\ : \implies \frac{10 - \sqrt{2} }{7}$

Required Answer,

$\frac{10 - \sqrt{2} }{7}$
