Forest stand’s growth of uneven-aged forests is represented by the logarithm equation:
log N = log k – a D log e
where:
• N= number of trees per diameter class
• D = DBH class
• e = base of natural logarithm
• k = number of trees at smallest DBH recognized – and index of relative density
• a = slope of line – the rate at which the number of trees logarithmically diminishes between
successive diameter classes
Explain how the logarithmic formula above would be transformed to predict and determine the
number of trees in a given diameter class of uneven-aged forest stands.

Andrew's parents follow a regular schedule for taking care of their car. They change the oil every 3 000 km, rotate the tyres every 10 000 km and replace the wiper blades every 15 000 km. After how many kilometres will they first have to change the oil, rotate the tyres and replace the wiper blades all at once?
