#18sqrt(2)#

Explanation:

#15sqrt(2)# is already simplified, but to simplify #sqrt(18)# , we need to figure out its factors.

the factors of #18# are #3, 3, and 2#

#sqrt(18)# simplified is #3sqrt(2)#

since #3 sqrt(2)# and #15sqrt(2)# both have the number #2# in the root you can add these two radicals to get
#18sqrt(2)#
