$3+sqrt3+sqrt5~~6.9681188$

As there is nothing common between the three, you cannot combine them except by converting them into decimals.

Hence $3+sqrt3+sqrt5$

$~~3+1.7320508+2.2360680$

= $6.9681188$

Since both $sqrt3$ and $sqrt5$ are irrational, the decimal equivalents can only be approximate. Hence, we write sum as $~~ 6.9681188$ .
