    [T-89 Ti]Help! How to setup 5th square of 25?

    Hi I just got my new Ti-89 Titanium calculator and there is one thing that is bugging me.

    on my last calculator I had to press [2nd] and then a botton that looked like x[square of].

    On my Ti, no button like this exists and I've got a test tomorrow and I'd really like to know how the heck this is done?

    A fast answer would be really helpful cuz im stuck atm

    Hello,

    I don't have titanium, but you can enter x^(1/n), which is the nth root of x

    Upgrade your OS

    For the TI89, you can upgrade your OS to the latest version (3.10) released in 2005.

    Once you upgrade. You can use the shortcut <> (Diamond) + 9 or type root(

    eg, to do the the 5th root of 25... type root(25, 5)
