3 cubed roots of Three is your solution.

To check your resolution (this simplest works on some of the problems), sq. or dice or fourth (whatever the root is of the unique drawback) the rest out of doors the root then multiply it by means of the inside.

So, for example: simplify the sq. root of 81x^7y^4z^5

Your resolution is:

9x^3y^2z^2(sqrt)xz

Square the 9x^3y^2z^2 and you get 81x^6y^4^z2.

Multiply 81x^6y^4z^2 by xz (within the sqrt) and also you get

81x^7y^4z^5, or your unique problem.
