just what I want is to see the imaginary unit right into a complex expression in EXACT MODE, may be also the user to choose by a flag, right or left

Optional parameters to handle just one command SOLVE.

SOLVE ( eq[s], [var], real/complex[flag], vareq[flag] )

The third argument (flag) indicates if you want to get real or (complex and real) answers, this argument is now available using SOLVE or cSolve, but why not make one SOLVE

the fourth argument indicates whether to include the variable, to view it as an equation y = sol, x =sol etc, This option is not available HPPRIME, I would like to see it as an optional flag. In the ti68k is defined by default =(

PD:

also required, a similar command QPI
(-8)^(1/3) => 1+√(3)*i
(-8.)^(1/3) => 1.+1.73205080757*i
exact(1.+1.73205080757*i) => 1+( 978122/564719 )*i =( => 1+√(3) *i.

(-8)^(1/3) => 1+√(3)*i +1 OK ( 1+√(3)*i )^3= -8
by pressing one second enter search other roots

(-8)^(1/3) [ENTER] 1+√(3)*i
[ENTER] -2
