Answer:

#3+sqrt3+sqrt5~~6.9681188#

Explanation:

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#.
