Roderick and Luke are both keeping track of a sample in Living Environment. Roderick analyzed his with the function R(n) = n3d and Luke created the function L(n) = n6d to keep track of the growth of his sample, where n is the initial amount of the sample and d is the number of days. Luke started with a population of 2, how many items did Roderick start with to achieve the same growth over time?
