#=> -8#

Explanation:

First solve for #x#:

#x = 2 + 2^1/3 +2^2/3#

#x = 2(3/3)+ 2/3 +4/3#

#x = (6+2+4)/3#

#x=12/3 =4#

Now substitute this value of #x# in given equation and evaluate:

#x^3 - 6x^2 +6x#

#=> 4^3 - 6\times4^2 + 6\times 4#

#=> 64 - 6\times16 + 6\times 4#

#=> 64 - 96 + 24#

#=> -8#
