Math Calculators, Lessons and Formulas

It is time to solve your math problem

You are here:

This calculator will eliminate a radicals in a denominator. It can rationalize radical denominators with 2 radicals or less.

To use it, replace radical sign with letter r.

Example: to rationalize $\frac{\sqrt{2}-\sqrt{3}}{1-\sqrt{2/3}}$ type r2-r3 for numerator and 1-r(2/3) for denominator.

Important: The form will NOT let you enter illegal characters (like y, p, ;, ...) How to input??

Examples

 $a)~~\frac{1}{\sqrt8}$ $b)~~\frac{1-\sqrt2}{1+\sqrt2}$ $c)~~\frac{3\sqrt2-2\sqrt3}{2\sqrt3+3\sqrt2}$ $d)~~\frac{6}{\sqrt{21}+\sqrt{7}+2\sqrt{3}+2}$ $e)~~\frac{\sqrt3+\sqrt2+1}{\sqrt3-\sqrt2+1}$ $f)~~\frac{1.1-\sqrt6}{\sqrt6-0.6}$
