What It Means to Rationalize the Denominator In order that all of us doing math can compare answers, we agree upon a common conversation, or set of rules, concerning the form of the answers. Simplify each expression by factoring to find perfect squares and then taking their root. Rationalizing the denominator is the process of moving any root or irrational number (cube roots or square roots) out of the bottom of the fraction (denominator) and to top of the fraction (numerator).. Then multiply the entire expression by . 1. If we multiply 23 2x2 by 23 … Then simplify. Since you multiplied by the conjugate of the denominator, the radical terms in the denominator will combine to 0. Objective: Rationalize the denominators of radical expressions.
