 Question 274564: I have been asked to take some figures from a 'yield table' of trees. Specifically the trees per ha/ and the diameters. I have then been asked to take the log base 10 of these figures, prior to plotting them on a graph. So in the first line (of many) I have 2309 trees with a diameter of 11 - what should I be doing with these figures. Am I to just move the decimal place?
