1. I can't do inequalities with the regular TI-89...but the titanium can. Is it possible to transfer the titanium os to the 89?

This is an SAT question. To answer this question I thought I could just solve the system of equations (a^(1/2)b^(1/2))^6 = 432 and a x b = z for z. But that doesn't work on my 89..(anyone with a titanium, try this out?)

I also wanted to try an solve for A x B straight up but the 89 says I can only solve for one variable. Any suggestions?

This goes back to the inequalities, can the 89 titanium do this?

Thanks.
