Question

Add: (5 + √7) (3 + 2√7)​

Answer 1

$= > (5 + \sqrt{7} )(3 + 2 \sqrt{7} ) \\ = > 5(3 + 2 \sqrt{7} ) + \sqrt{7} (3 + 2 \sqrt{7} ) \\ = > 15 + 10 \sqrt{7} + 3 \sqrt{7} + 14 \\ = > 29 + 13 \sqrt{7}$

Hope it helps :)

Answer 2

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

$\implies5(3+2 \sqrt{7} )+\sqrt{7} (3+2 \sqrt{7} ) </p><p> \implies15+10 \sqrt{7} +3 \sqrt{7} +14 \ \implies29+13 \sqrt{7} </p><p>$
