Alex,

Solve[x^3 - 1 == 0][[2]]
{x -> -(-1)^(1/3)}

Usually I would first evaluate

Solve[x^3 - 1 == 0]

to see all the solutions. Then I would select the solve statement and use
the BasicInput palette to add the part position.

I am solving a cubic equation and I got 3 roots. How can select root
number 2 for processing?

Thanks,

Alex
