I suggest to do a Google search and at least read a couple pages that give the classical rules for simplifying radical expressions. You may still have some critique but will at least know what you are criticizing. Question as stated shows lack of familiarity with basics.

P.s. 2*fifthroot(162) is the classical answer.

P.s. $2 \sqrt[5]{162}$ is the classical answer.

Google the web for simplification rules. Stuff like no radicals in the denominator, no powers in the radical, etc. The first page of a search gives several good links.

If you want to complain about simplification after that, then fine. But your question as it is now shows a lack of effort.
