You have to use a calculator or leave the expression as $3 \sqrt{5} + 2 \sqrt{2}$ $3sqrt5+2sqrt2$ .

$3 \sqrt{5} = 6.708203932499$ $3sqrt5=6.708203932499$
$2 \sqrt{2} = 2.828427124746$ $2sqrt2=2.828427124746$

$3 \sqrt{5} + 2 \sqrt{2} = 6.708203932499 + 2.828427124746 = 9.536631057245$ $3sqrt 5+2sqrt 2=6.708203932499+2.828427124746=9.536631057245$
