The natural logarithm is often written as ln which you may have noticed on your calculator. lnx = loge x The symbol e symbolizes a special mathematical constant. It has importance in growth and decay problems. The logarithmic properties listed above hold for all bases of logs. If you see logx written (with no base), the natural log is implied.
