How to Rationalize a Radical Out of a Denominator

WebSep 1, 2024 · When an expression involving square root radicals is written in simplest form, it will not contain a radical in the denominator. We can remove radicals from the denominators of fractions using a process called rationalizing the denominator. We know that multiplying by 1 does not change the value of an expression. WebInstead, to rationalize the denominator we multiply by a number that will yield a new term that can come out of the root. For example, with a cube root multiply by a number that will give a cubic number such as 8, 27, or 64. rationalizing the denominator higher root Algebra 2 Roots and Radicals making red sauce from scratch https://boudrotrodgers.com
