How to Simplify Radicals?

To simplify radicals that are square root radicals, you need to look at the number under the radicand and try to find square factors. For example, sqrt(8) can be factored as sqrt[ 4x 2]. Since 4 is a square, you can then simplify the radical by writing it as 2sqrt(2). There also online calculators that simplify radicals. You can find more information here:
