An error has been made in evaluating this limit. Which numbered line of the evaluation of this expression represents the introduction of an error regarding the use of the limit laws? (Assume that the limit exists and that h(x) is never equal to zero) limxa{cf(x)g(x)f(x)[h(x)]2}(1)=climxa{f(x)g(x)f(x)[h(x)]2}(2)=climxa[f(x)g(x)f(x)]limxa[h(x)]2(3)=climxa[f(x)g(x)f(x)][limxah(x)]2(4)=climxaf(x)limxa[g(x)f(x)][limxah(x)]2(5)=climxaf(x)limxag(x)limxaf(x)[limxah(x)]2 Line (1) Line (2) Line (3) Line (4) Line
