      log2 log5 logx+log2 logy = log(x (log2)=(log5))+log(2) = log(2 x): Thus the functional relationship is: y = 2 x (log2)=(log5) = 2 x 0:43. Alternative answer to Problem # 6: Since we have a straight line in a log-log plot, a linear relationship in a log-log plot corresponds to a power relationship between the original quantities.
