if the multiplication involves the same radical, (squarel root, cube root, etc.) then that is equal to the product of the radicals
ie sqrt(5) * sqrt (2) = sqrt(10).
if they are different radicals, then it is more difficult. the only way is to change the radical to the same radical through manipulation of the number/radical.
for example 4 * sqrt (2) = sqrt (4^2) * sqrt (2) = sqrt (16) * sqrt (2) = sqrt(32).

when you multiply radicals, (on what's under it first), if they're the same, the radicals cancel out and you are left with that number. If they are different you multiply those two numbers under the radical, and simplify if necessary.

sqrt(x) * sqrt(y) = sqrt(xy)
If you would like to give me some problems, i can show you a lot more.
