EXAMPLE 6 Evaluate lim x In(x5). x ? 0+ SOLUTION The given limit is indeterminate because, as x? 0+, the first factor (x) approaches while the second factor In(x5) approaches -?o. Writing x = 1/(1/x), we have 1/x ? ? as x ? 0+, so l'Hospital's Rule gives lim_x In(x5) = lim In(x5) x ? 0+ X? 0+ 1/x 5/x = = = lim x ? 0¹-1/x² lim X? 0+
EXAMPLE 6 Evaluate limx?0+?xln(x5). SOLUTION The given limit is indeterminate because, as x?0+, the first factor (x) approaches while the second factor ln(x5) approaches ??. Writing x=1/(1/x), we have 1/x?? as x?0+, so l'Hospital's Rule gives x?0+lim?xln(x5)?=x?0+lim?1/xln(x5)?=x?0+lim??1/x25/x??
