See the above attachment for answer.

Answer 2

Answer:

${ \large{ \underline{ \sf{Solution}}}}-$

$: { \implies{ \rm{ \frac{5}{ \sqrt{7} - \sqrt{2} } }}}$

$: { \implies{ \rm{ \frac{5}{ \sqrt{7} - \sqrt{2} } \times \frac{ \sqrt{7} + \sqrt{2} }{ \sqrt{7} + \sqrt{2} } }}}$

$: { \implies{ \rm{ \frac{5( \sqrt{7} + \sqrt{2}) }{ {( \sqrt{7}) }^{2} - ({ \sqrt{2}) }^{2} } }}}$

$: { \implies{ \rm{ \frac{5 (\sqrt{7} + \sqrt{2}) }{7 - 2} }}}$

$: { \implies{ \rm{ \frac{5 (\sqrt{7} + \sqrt{2}) }{5} }}}$

$: { \implies{ \rm{ \frac{{ \cancel{5}} (\sqrt{7} + \sqrt{2}) }{{ \cancel{5}}} }}}$

$: { \implies{ \rm{ \sqrt{7} + \sqrt{2} }}}$

${ \therefore{ \underline { \rm{The \: Answer \: is \: \sqrt{7} + \sqrt{2} }}}}$
