follow the above steps

Answer 2

Answer:

$= \frac{ \sqrt{5} + \sqrt{3} }{ \sqrt{80} + \sqrt{48} - \sqrt{45} - \sqrt{27} }$

$= \frac{ \sqrt{5} + \sqrt{3} }{4 \sqrt{5} + 4 \sqrt{3} - 3 \sqrt{5} - 3 \sqrt{3} }$

$= \frac{ \sqrt{5} + \sqrt{3} }{ \sqrt{5 + \sqrt{3} } }$

$= \frac{ \sqrt{5} + \sqrt{3} }{ \sqrt{5} + \sqrt{3} } \times \frac{ \sqrt{5 } - \sqrt{3} }{ \sqrt{5} - \sqrt{3} }$

$= \frac{ (\sqrt{5} + \sqrt{3})( \sqrt{5} - \sqrt{3} ) }{ (\sqrt{5} + \sqrt{3})( \sqrt{5} - \sqrt{3} ) }$

$= \frac{5 - 3}{5 - 3}$

$= \frac{2}{2}$

$= 1$
