hellocan u tell me about real value of(-2) ^(2/6).Whether the expression is real or not.....also comment about (-2) ^(1/3)

(-2) ^(2/6)=(-2) ^(1/3)=e^{(ln(2)+i(2n+1)π)/3}, where n is ANY integer

If a^(m/n) is nth root of a^m.............Considering this statement to be true

can we say (-2)^ (2/6) will be 6th root of (-2)^2.....

and can we say that(-2)^(1/3) is 3rd root of -2= negative of third root of 2
