See a solution process below:

Explanation:

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)
