For the following equation, I want to get only the solutions for z where z is real: Reduce[13219.56 == 20000/1.95583 * (1 + z)^11, z] It is suggested that one uses Reduce[13219.56 == 20000/1.95583 * (1 + z)^11, z, Reals] But I use Mathematica 4 and it seems that Reduce does not have this option in this Mathematica version. Can I anyway constrain the solution space with Mathematica 4? Thanks in advance M. Harborth.
