-(3√6+32)

Answer 2

Step-by-step explanation:

add (5√2 + 7√3) and (√2 - 2√3)

$\bf = > (5 \sqrt{2} + 7\sqrt{3} ) + ( \sqrt{2} - 2 \sqrt{3} ) \\ \\ \bf = > 5 \sqrt{2} + 7 \sqrt{3} + \sqrt{2} - 2 \sqrt{3} \\ \\ \bf = > 5 \sqrt{2} + \sqrt{2} + 7 \sqrt{3} - 2 \sqrt{3} \\ \\ \bf = > \{(5 + 1) \sqrt{2} \} + \{(7 - 2) \sqrt{3} \} \\ \\ = > \bf6 \sqrt{2} + 5 \sqrt{3}$

So,

the addition is 6√2 + 5√3.
