    Let's have q for the quarterly rate of interest and r for the annual rate, shall we? :) Then we have this relation... \[\Large (1+q)^4 = 1+r\]

    yes, but that's equal to 0.08. Now just solve for q :)

    Well, for starters, get the fourth root of both sides?\[\Large 1+q = \sqrt[4]{1.08}\] And work it out from here
