y and z are known numberic values
z = x^y
How do I ask FoxPro to solve for x?
My usage is to find out the compounded return over a certain period of
time. For instance, if an investment account is increased by a factor of
6 in 8 years, what is the percent annual return, compounded. I believe
the mathematical question above solves that when z=the increment factor
(6 in this case), x is the return (e.g. 1.10 for a ten percent return),
and y is the number of years.
Thanks!
Dan

x = exp(log(z)/y)
