Question 302013
Please help to isolate "x" in the following equation:
{{{y=a/(1+x)^n}}}
-------------------
{{{(1+x)^n = a/y}}}
Multiply by y
{{{y(1+x)^n = a}}}
Divide by 1+x
(1+x)^n = a/y
Take the nth root
{{{1+x = (a/y)^(1/n)}}}
{{{x = (a/y)^(1/n)) - 1}}}
---------------------------
{{{6000=9720/(1+x)^3}}}
x = (9720/6000)^(1/3) - 1
x = 0.17446
