Suppose a fraction a b a b contains a radical in the denominator. Rationalizing the denominator is a method of simplification that eliminates radicals from the denominator. The numerator may contain radicals, but we generally don’t worry about that. Only the denominator is rationalized. Sure, for example, if we have the fraction 3/√2, we can rationalize the numerator by multiplying both the numerator and denominator by √2. This gives us (3*√2)/ (√2*√2) = (3√2)/2. Now, the radical is in the denominator and the fraction is rationalized. 5.BSMSMSTMSPHD. Sep 4, 2006. In summary, the conversation discusses the reasoning behind teaching algebra students to rationalize the denominator of a fraction containing a radical. While there is no mathematical reason for this convention, it is often desirable for simplifying and comparing expressions. In this video, we explore how to find the limit of a function as x approaches -1. The function is (x+1)/ (√ (x+5)-2). To tackle the indeterminate form 0/0, we "rationalize the denominator" by multiplying the numerator and denominator by the conjugate of the denominator. This simplifies the expression, allowing us to evaluate the limit.
