help me with this algebra please.
i'm stumped. help me find X
A=B(1+X)^n I've been trying to figure it out for the past hour. It is basically the time value of money equation. the unknown is the rate (X) A=new value B=old value n=# of periods

Dear Algebra,
I don't know where your X is, nor do I care Y they haven't come back. Yours truly, Me

LOL
This would be a problem I'd have my daughter look at later tonight to see if it makes sense to her. She's in advanced Algebra II at her high school. I'll let you know what she comes up with...

nope. it will take an algebra genius to get this right. if A=121, B=100, n=2 then X=10% i can use a HP 12c financial calculator but I can't figure out the algebra part

If you plug those numbers into the equation TheDon offered, doesn't it work for you? It does for me.

Just quickly, since I hate these problems.
EDIT: nevermind, I got it... x=(a/b)^(1/n)1

If you have Excel on your computer, you can simply type any formula you want into the cells and then plug values in and it will do the calculations for you.
