Answer 2

$\huge \fcolorbox{red}{purple}{question \: :}$

$(3 \sqrt{2} + 7 \sqrt{3} ) \: + \: ( \sqrt{2} - 5 \sqrt{3} )$

$\huge \red{ \fbox{{ANSWER \::}}}$

$(3 \sqrt{2} + 7 \sqrt{3} ) + ( \sqrt{2} - 5 \sqrt{3} )$

$\\ = 3 \sqrt{2} + 7 \sqrt{3} + \sqrt{2} - 5 \sqrt{3}$

$= 3 \sqrt{2} + \sqrt{2} + 7 \sqrt{3} - 5 \sqrt{3}$

$= \sqrt{2} (3 + 1) + \sqrt{3} (7 - 5)$

$= \sqrt{2} (4) + \sqrt{3} (2)$

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