Since we have a cube root in the numerator, we need to multiply by the cube root of an expression that will give us a perfect cube under the cube root in the numerator. If the denominator is a binomial with a rational part and an irrational part, then you'll need to use the conjugate of the binomial. For this reason, a process called rationalizing the denominator was developed. Related Symbolab blog posts. 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).

In each case the expression is rewritten so that radicals are removed (from either the numerator or denominator). To rationalize the denominator, you must multiply both the numerator and the denominator by the conjugate of the denominator. 2. This part of the fraction can not have any irrational numbers. After those simplifications, we rationalize the denominator by multiplying both the numerator and denominator with the square root in the denominator. Rationalize the Numerator. Combine. In this scenario, dividing $1$ by $\sqrt{3}$ is a lot harder than dividing $\sqrt{3}$ by $3$, so rationalizing the denominator (rather than rationalizing the numerator) seems logical. The good news: it's usually not very difficult to rationalize the denominator, and you can always double check your work with our calculator. To do that, we can multiply both the numerator and the denominator by the same root, that will get rid of the root in the denominator.
