New Rate

 A small finance problem for this morning: I have 100$

to invest for four years. At 2% compound interest, I am

ending up with 108.24$ at maturity. 



I want to do better, and go for a 10$ return in the same period.

What should my new interest rate be. My unknown is the log base,

and whatever that is, to the fourth power, yields a multiplier of 1.1

for my investment (of 100$).

log(base(x))1.1 = 4


ln(1.1)/4=0.0238...



My new interest rate  is 2.3827
