1. Write the prime factorization of the radicand. StartRoot 324 EndRoot = StartRoot 2 times 2 times 3 times 3 times 3 times 3 EndRoot 2. Apply the product property of square roots. Write the radicand as a product, forming as many perfect square roots as possible. StartRoot 2 times 2 times 3 times 3 times 3 times 3 EndRoot = StartRoot 2 squared EndRoot times StartRoot 3 squared EndRoot times StartRoot 3 squared EndRoot 3. Simplify. =

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
