Calculator Question Geometric Mean figure, easily, example, average, equation

busprof

How do you input the “T” of the Geometric Mean using the BAII?
I know the equation and I can easily figure out the average, I don’t know how to input the “5th” power of a square root, for example?
Any help would be greatly appreciated!
Thanks
Jake

Jake, there is a key x^y. you press that when you have to press in a power number.

it is the Y^x (the key just above the 9).
If using the BAII I highly advise you go to the TI website and they have step by step web videos on how to use the calculator. Shows you how to do, NPV’s, Statistics, bond calcs, mortgage calcs, annuity calcs and use the memory functions

Is there a way to input the 5th root of a number directly?
I use x^ 0.2 to find the 5th root of x.

Got it!
Although 80 explained it well, I think heading to the TI site might be a good idea in general.
Thanks again for the help!

For the BA II you just need to use y^x key with inputs y^(1/x). X being the root you want to take.

Am I alone in prefering 12c in most cases?

Can we use the hp 10BII calculator for the level 1 exam? . I already have that so was wondering and I can do everything that I need to do.

Nope apparently there are ways to save formuli in it. I used the HP10B all the way through University but had to switch to the TI BA II for CFA LI exam. Glad I did, once I became familiar with it I found I was actually easier to use.
