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

You want to find out the cube root of 1.183?
If yes then follow these steps:
Step 1 … Enter 1.183
Step 2 … Press y^x (the key above number 9)
Step 3 … Enter 3
Step 4 … Press 1/x button (the key above y^x)
Step 5 … Press =
You will get 1.0576

ok i’ve read this post because I thought it may help me in using the calc and geometric mean but I am getting super confused regarding the 3rd root. As an example if I have the following question how do i get to the answer using the calc;
?y??1.183 1 = 1.0575
thanks to anyone who can help on this simple questions

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.

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.

No, your’e not.
I’m with you.

Am I alone in prefering 12c in most cases?

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.

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!

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.
