Do you recall the name of these two binomials?

  6√15 = 2√5

    4√10 = 12√2

Finally, Division....

In order to simplify an expression such as √3 √5we have to perform a Procedure called "Rationalizing The Denominator"

In other words, we have to come up with a way to make the Denominator Rational!
