You can put this solution on YOUR website!
17000=10000%281%2Bi%29%5E5 Start with the given equation.


17000%2F10000=%281%2Bi%29%5E5 Divide both sides by 10000.


1.7=%281%2Bi%29%5E5 Divide


root%285%2C1.7%29=1%2Bi Take the fifth root of both sides.


1.112=1%2Bi Take the fifth root of 1.7 to get 1.112


1.112-1=i Subtract 1 from both sides.


0.112=i Subtract.



So the solution is approximately i=0.112. Are you sure that the answer is 11.20? If you are then I would double check the problem.
