pdf ico   A.4 Rationalizing the Denominator

This knowledge is useful when a radical expression has a binomial in the denominator, such as 10 3 – 7. To rationalize the denominator, we use the conjugate of the denominator as the common multiplier. For example, to rationalize the denominator of 10 3 – 7, the common multiplier is 3 + 7 , so we multiply the fraction by 3 + 7 3 + 7: 10 3 – 7
