Math Lessons, Calculators and Homework Help

It is time to solve your math problem

You are here:

The following calculator can be used to simplify ANY radical expression.

To use it, replace radical sign with letter r .

Example 1: to simplify $(\sqrt{2}-1)(\sqrt{2}+1)$ type (r2 - 1)(r2 + 1).

Example 2: to simplify $\left( \frac{2}{\sqrt{3} - 1} + \frac{3}{\sqrt{3}-2} + \frac{15}{3- \sqrt{3}}\right)\cdot \frac{1}{5+\sqrt{3}}$ type (2/(r3 - 1) + 3/(r3-2) + 15/(3-r3))(1/(5+r3)).

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