8%2F%286%2Asqrt%2815%29+%29++++++++++++++++++

In order to rationalize the denominator, you must multiply numerator and denominator of this fraction by sqrt%2815%29+.



%288%2Asqrt%2815%29%29%2F%286%2A15%29+

Divide out the factor of 2 in the numerator and denominator:
%284%2Asqrt%2815%29%29%2F%283%2A15%29
%284%2Asqrt%2815%29%29%2F45

If you need additional help with rationalizing denominators, please see my own website by clicking on my tutor name "Rapaljer" anywhere in algebra.com. Then look for the link on my homepage called "MATH IN LIVING COLOR." Select Intermediate Algebra, and look for Chapter 3, then the section called "Rationalizing Denominators." I think you will find my explanations which are IN COLOR helpful!!
