Question 835128: Ms. Dinero wants to invest $2,300 compounded annually for 6 years with a balance of $4,200 at the end of that time period. At what rate would she have to invest her money to achieve that goal? (Round to the nearest hundreth)
I set up the compound interest formula like this: 4200=2300(1+(x/1))^6 but don't know what to do after I divided each side by 2300. Help please! I can't figure out how to get the variable alone

4200=2300%281%2B%28x%2F1%29%29%5E6
%281%2Bx%29%5E6=42%2F23
1%2Bx=%2842%2F23%29%5E%281%2F6%29
x=%2842%2F23%29%5E%281%2F6%29-1
or approximately
x=.10557
