See a solution process below:

First, rewrite the expression as:

#(9 * 4)(sqrt(2) * sqrt(6)) => 36(sqrt(2) * sqrt(6))#

Next, use this rule for multiplying radicals and it's reverse to complete the simplification:

#sqrt(a) * sqrt(b) = sqrt(a * b)# and #sqrt(a * b) = sqrt(a) * sqrt(b)#

#36(sqrt(2) * sqrt(6)) => 36sqrt(2 * 6) => 36sqrt(12) =>#

#36sqrt(4 * 3) => 36(sqrt(4) * sqrt(3)) => 36(2 * sqrt(3)) =>#

#(36 * 2)sqrt(3) =>#

#72sqrt(3)#
