Recall that one method for treating this type of limit is by taking the natural logarithm. If we let y = [f(x)]?(x),then In(y) = g(x) In (f(x)). Applying this method gives the following result.y = (1 - 5x)1/xIn(y) = ¹/in(1-([× )x)We note that this leads to an indeterminate product on the right side, which is of type
