The power function,
and
model two different data sets of trees. Each function can be used to estimate the biomass M (in kilograms) of a tree above ground, where d is the diameter (in centimeters) of the tree 4.5 feet above the ground. Biomass is the mass of all living things including the tree and anything living in the tree. Rewrite the functions using rational exponents. Then, determine how many times greater the biomass of a tree with a diameter of 20 centimeters from the data set of A is compared to a tree of the same diameter from data set B.
