The average daily metabolic rate for rodents can be expressed as a function of weight by m = 90w^0.6, where m is the metabolic rate (in kcal/day) and w is weight(in kg). Find the weight of a rodent whose metabolic rate is 154 kcal/day.
--------------------
154 = 90*w^0.6
-------
w^0.6 = 154/90 = 1.711
-----
w = 1.711^(1/0.6) = 1.711^(10/6) = 1.711^(5/3) = 1.4479 kg
