If you're trying to simplify a radical expression that has both integers and variables, you''ll want to simplify each piece separately. Rewrite the integer as a product of two integers, one of which is a perfect square. Reduce from there. For the variables, break the exponent into groups of two (like xsquared's) because each root of xsquared will become regular x outside the root. Do this process for each variable. Your final result will be the product of all of the numbers and variables outside the radicals, times the product of all of the numbers and variables that were left inside the radical.
