4*sqrt(2) * 2 * sqrt(3)
Multiply the integers together first. 4*2 = 8
Now the radicals. This is a little harder, but the question gave you one break: the numbers under the radical are prime and different, so the question is not going to break down any further.
sqrt(2) * sqrt(3) = sqrt(2*3) = sqrt(6)
So your answer is 8 sqrt(6)
