Alissa is currently a teacher in the San Francisco Bay Area and Brightstorm users love her clear, concise explanations of tough concepts
When multiplying two radicals, you would get the correct answer if you multiplied the radicands first and then reduced later, BUT you'd be working with very large numbers. A tip presented here is to simplify each radical first on its own, and then multiply the numbers outside, and multiply the numbers inside. You should get the same result as the previous method, but arrive at it with much smaller numbers, and more likely without a calculator.
