Today JPaul and I discusded how to rationalize radical expressions. I explained to JPaul that it's considered "bad math" to leave radicals/roots in the denominator. To rid the denominators of these roots we must use a process called rationalizing. If we see the square root of a number, we multiply by itself. If there are two terms in the deminator, we multiply by the conjugate. We used the "I do, we do, you do" method of practicing these problems.
