fractional exponents

Can you give a clear explanation as to when fractional exponents can be reduced (or expanded)? For example (8)^(1/3) does not equal (8)^(2/6), as this second item has 6 roots (some of them complex) and the first item has only 3 roots. So by reducing 2/6 to 1/3 roots are eliminated. My notation (8)^(1/3) means (8) raised to the (1/3) power.
