25000=11000(1+r)^4
25000=11000(1+r)^4 divide both sides by 11000
(25/11) = (1 + r)^4 take the positive 4th root of each side
(25/11)^(1/4) = 1 + r subtract 1 from both sides
(25/11)^(1/4) - 1 = r = 0.2278 = about 22.78%
If 4 is the number of years, then r=22.78% compounded annually.
If 4 is the number of quarters in 1 year, then r=59.28% compounded quarterly
