Answer 2

Step-by-step explanation:

$\boxed\leadsto\small\bold\blue{Answer}$

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

$by \: using \: (a + b)(c + d) = ac + ad + bc + bd$

$= 3 \times 2 + \sqrt[3]{2} + \sqrt{5 \times 2 } + \sqrt{5} \sqrt{2}$

$= 6 + \sqrt[3]{2} + \sqrt{5 \times 2} + \sqrt{5} \sqrt{2}$

$=6 + \sqrt[3]{2} + \sqrt[2]{5} + \sqrt{5} \sqrt{2}$

$=6 + \sqrt[3]{2} + \sqrt[2]{5} + \sqrt{10}$
