RE: HP 50G "Bad Argument Value"
I'd suggest using the numeric solver (ROOT) instead of SOLVE or SOLVEVX because those use CAS logic to look for a symbolic result. ROOT uses numeric methods to find one root at a time near a given initial guess.
In RPN mode: 'X^40=13^X' 'X' 1 (or whatever guess you want to start at) ROOT > 1.07109628939 With an initial guess of 1 you get another root, 0.941418703497 Also try an initial guess of 65. Finding ALL the roots is left as an exercise for the student. ;) <0ΙΈ0> Joe
