Rationalizing the Denominator In addition to simplifying the numerator and the denominator in a fraction, it is mathematical convention to rationalize the denominator--that is, to write the fraction as an equivalent expression with no roots in the denominator. {3}

Example problems have radicals with variables and use conjugates to rationalize. $$
Rationalizing the Denominator by Multiplying by a Conjugate Rationalizing the denominator of a radical expression is a method used to eliminate radicals from a denominator. In a case like this one, where the denominator is the sum or difference of two terms, one or both of which is a square root, we can use the conjugate method to rationalize the denominator. Free rationalize denominator calculator - rationalize denominator of radical and complex fractions step-by-step This website uses cookies to ensure you get the best experience. The reasoning and methodology are similar to the "difference of squares" conjugate process for square roots. Find the conjugate of . Rationalize the Denominator with Conjugates. In order to rationalize the denominator, you must multiply the numerator and denominator of a fraction by some radical that will make the 'radical' in the denominator go away. Rationalization is the process of removing the imaginary numbers from the denominator of an algebraic expression. \frac{ 9}{ 3 + \sqrt{5} }

About "Rationalizing the denominator with variables" When the denominator of an expression contains a term with a square root or a number within radical sign, the process of converting into an equivalent expression whose denominator is a rational number is called rationalizing the denominator. \\
