Problem w/ a negative number raised to a decimal..

[hgaon001]

What is (-1)^2/3 equal to ?

3/2[0 - (-1)^2/3 ] = ? My book says this = -3/2
Any help on why this is true would be great.

The calculator gives me an error when i plug it in

\(\displaystyle (-1)^{\frac{2}{3}} \, = \, [(-1)^{2}]^{\frac {1}{3}}\)
