# 12sqrt6+8sqrt15+12+4sqrt10 #

Explanation:

1)Multiply the brackets:
# 4sqrt3 * 3sqrt2=12sqrt6 #
# 4sqrt3 * 2sqrt5=8sqrt15 #
# 2sqrt2 * 3sqrt2=12 #
#2sqrt2 * 2sqrt5=4sqrt10 #

2) Add together
In this instance nothing can be added as no roots are the same or there is no other number apart from 12 to be added, so therefore we can't add anything.
so the answer simply stays as:
# 12sqrt6+8sqrt15+12+4sqrt10 #
