Multiply the numerator and denominator by the given radical to have a rational number in the denominator, and further simplify the expression. To rationalize the numerator, 23 2x2, we multiply the numerator and denominator by a factor that will make the radicand a perfect cube. 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).. o 9 lM da gdCes Fwoi5toh l 5IGnJf dian9i Ztwe2 HAHl Rgveob3r na4 61 J.U Worksheet by Kuta Software LLC Work your way through these pdf worksheets to hone your skills in rationalizing the denominators.
